"Sorry, we failed you. Try refreshing!" when browsing Reddit on Google Chrome

For so long I was getting the following error when trying to view Reddit on Chrome on my laptop.

"Sorry, we failed you. Try refreshing!" 

This (for me):

• Only occurred on my laptop
• Only happened in Google Chrome

It bugged me for ages but often didn't have a moment to sit down and work out the problem but tonight had the chance.

I tested and confirmed that it worked fine in Edge, removed AdBlocker and with no signs of a fix.

So I did the most Level 1 Help Desk resolution... cleared the browser cache.

Fixed!

I figured there must have been something in the cache or cookies that was trying to load older versions or authentication of the site that were causing conflicts, resulting in the above error.

Surprisingly, there weren't that many articles about this issue, nor advising of simple things like clearing the cache. I even saw one guy to advise to just change their entire browser preference. A bit extreme I thought.

Deleting Office 365 Tenant

For a long time now, I have been using trials to test new technologies at home that I can use for my work like every good tech does. With the introduction of Office 365, more and more I need to be able to test the clouds services for different scenarios. However, I like to completely remove any services that I am finished with an no longer need as a end-of-the-day clean up task.

So how do you do this with Office 365?

By default, once the trial subscription expires the tenant will remain active allowing you a chance to purchase a new subscription and assign to your tenant. In this case I know I will never need the tenant again.

So this is what I have found to decommission a Office 365 trial tenant using Azure Active Directory.

WARNING!

Please triple check that you are doing this on the correct tenant. This deletion is unrecoverable. You do this at your own risk.

Prerequisites

Before you can start this process you need to make sure:

• All subscriptions are deprovisioned
  This can be viewed in the Office 365 Subscriptions portal
• All users have been deleted
  The primary admin account needs to be remaining with no licenses assigned

Procedure

1. Logon to https://portal.azure.com/
2. Go to All Services 
3. Search for "Directory" and Select Azure Active Directory 
4. Select Delete Directory
   
5. A check will be done to make sure all services have been decommissioned 
1. All user accounts, App registrations, enterprise applications need to be deleted 
2. Subscriptions should be Deprovisioned 
3. Have full access to the Azure AD directory
4. If you don't, it will provide a link to fix this. 
5. No MFA enabled 
6. If all the above is cleared, you will be allowed to delete the directory. 

Once deleted, you will need to log out. After a moment, you won't be able to sign into the account, confirming the deletion of the tenant.

Microsoft's end of Windows 10 Mobile

This month we have heard from Microsoft that Windows 10 Mobile is no longer a focus and will no longer developing the platform. For me, this a long time coming but still a sad day.

I started my Windows Phone journey with the Samsung Omnia 7 running Windows Phone 7. As with the image above, it wasn't as great as the iPhone 4 that I was sporting at the time, but I had gotten it as a trial.

What I liked about it was it was fast, and everything was integrated. The People Hub and Messaging was amazing. I could send SMS, MMS, and Facebook messages all from the one app. and this carried on to the Windows Phone 8.

I made the next step by getting the Nokia Lumia 920 running Windows Phone 8. I had this phone for two years without fail. It was a great phone. Windows Phone 8 was definitely the peak of the line for Windows Phone.

On this device, it did everything and more than even Android and iOS even do today out of the box. My most beloved feature was the in-car features. While I was driving and received a text, it would read the messages to me and I could reply by voice. And it work almost flawlessly. They took this out in Windows 10 Mobile.

While most people would make fun of the fact I had a Windows Phone and I didn't have the availability of the apps they did on other platforms, the apps I did use worked well. I had what I needed and it supported the few I needed.

Windows Phone 8 integrated perfectly with Windows 8 at the time also. Passwords saved in Windows would automatically be available for me on my phone. It was great.

Over time, even in the Windows Phone 8 days, the writing was on the wall. More developers stopped updating their apps and Microsoft would provide less feature updates. I made the choice to give the benefit of the doubt and went with the Microsoft Lumia 950, but it was a mistake.

Most of the features I liked in the Lumia 920, didn't exist in the 950 thanks to Windows 10 Mobile. It was another OS and acted very differently despite the same interface. After dropping my Samsung Galaxy 7 Edge, I was forced to use it on my four week trip to the Philippines and it worked very well, I'll give it that. However it continued as more devs and apps dropped support for the phone and platform. While some will say that this was due to the change in platform to the new UWP, most just killed the old app but didn't develop a new one.

I had a love hate relationship with my Windows Phone, but I stood by them in hopes it would become something more. But Microsoft did nothing to help the situation. In changing from Windows Phone 7, Windows Phone 8, Windows Phone 8.1 and Windows 10 Mobile, they had different code based which all put more efforts on the developers which by Windows 10 Mobile there was little to no reason to continue to redevelop. And I understand their frustration.

The idea Microsoft had for Windows Phone was great and I think ahead of its time, but the execution and handling was poor.

Since signing up for the Lumia 950 in 2015, I have since had a Samsung Galaxy 7 Edge and now using the iPhone 8 and in both platforms the experience is much better but still wish that Windows Phone had more.

PowerShell: Download and Install Java 8 JRE

This script I wrote for our automation system that will:

1. Download the latest Java 8 JRE from Java.com
2. Save in a local directory C:\Install
3. Create a Install Options File
4. Run the installer silently with the necessary Installer Options

The Installer Options file determines what configuration is used the install of Java.

For example, in the script I have configured. This will perform a silent install, auto updates enabled, no reboot after the installation, Sponsors/ads install disabled and will uninstall any older existing installations of Java JRE.

• INSTALL_SILENT=Enable
• AUTO_UPDATE=Enable
• REBOOT=Disable
• SPONSORS=Disable
• REMOVEOUTOFDATEJRES=Enable

You can find these and other options to use from the Java website:

https://docs.oracle.com/javase/8/docs/technotes/guides/install/config.html#installing_with_config_file

This has been tested to work on PowerShell v2 and higher.

PowerShell: BATCH Script to Allow PowerShell Scripts to Execute

For some SysAdmins, they will use one or more tools to deploy software to a range of computers on their network. For me, it our monitoring tool that allows are to remote execute scripts to do some sort of task.

Writing in PowerShell is amazing and is Microsoft's best yet command line tool. However by default for security purposes, script execuition is blocked for untrusted or unsigned scripts.

I won't go into Signing scripts just now but using the following command will allow you to run PowerShell Scripts

Set-ExecutionPolicy -RemoteSigned

This line still provides a level of protection while still allwoing you to execute custom scripts. Other switches include -bypass and -unrestricted.

So how can we get a large number of these set?

There are a number of ways:

1. Group Policy
2. Batch Script

The reason for me writing this BATCH Script is that it allows me to deploy and run on a computer regardless of the Domain it is joined to.

Copy and paste this code into a text file called SetExecutionPolicy.bat and then Save.

This script also creates entries into the Windows Event Viewer to tell you if and when the command has been executed, or if it failed to run.

@echo off

PowerShell: Download and Install Citrix Receiver

I have been doing quite a bit of work lately on PowerShell scripting for work and this is a common one we deploy to our clients that use Citrix.

This script does the following:

1. Creates the folder C:\Install\CitrixReceiver
2. Downloads the latest Citrix Receiver software from the Citrix website
3. Installs the downloaded Receiver silently

The link for the Citrix Receiver is: http://downloadplugins.citrix.com/Windows/CitrixReceiver.exe

Works with PowerShell v2 and higher.

A lot of my scripts are built to work at this level as it means that I can deploy my scripts to older machines without having to first upgrade PowerShell.

Copy and paste the code into a text file called InstallCitrixReceiver.ps1.

EATON IPM Appliance: Update IP address

The EATON Intelligent Power Manager is a software package that help monitor and manager UPS connected to your server infrustracture and can be installed in different ways. For virtual environments, the easiest way is to deploy the pre-configured Virtual Appliance for VMware ESXi.

However what I discovered is there is no easy way to reconfigure the IP addresses just from the management console. As the appliance is based on Centos Linux, you can use basic Linux commands to change the IP address.

For this, you will need either direct console access or SSH.
As you will be changing the IP address and a disconnection will be required, I advise connecting via the direct console.

1. Log on to the Virtual Appliance as root
   (Default username is 'root'; default password is eaton)
   
2. Use vi to modify the ifcfg-eth0 file
   
   #vi /etc/sysconfig/network-scripts/ifcfg-eth0
   
   Update with the following lines:
   DEVICE=eth0
   BOOTPROTO=static
   ONBOOT=yes
   TYPE=Ethernet
   IPV6INIT=no
   IPADDR=x.x.x.x
   NETMASK=255.255.255.0
   
   Then, save and close (:wq)
   
3. Use vi to modify the sysconfig/network file
   
   #vi /etc/sysconfig/network
   
   Update with the following lines:
   NETWORKING=yes
   NETWORKING_IPV6=yes
   HOSTNAME=localhost
   DOMAINNAME=localdom
   GATEWAY=x.x.x.x
   
   Then, save and close (:wq)
   
4. Restart the network service to have settings take affect
   
   #service network restart
