When you upgraded a NetScaler from firmware version 10.5 to 11.0, there were many things you needed to be aware of which I covered in my “Citrix NetScaler 10.5 to 11.0 firmware upgrade issues to watch out for” article. I really love 11.1 and all the improvements over the older firmware but one of these issues is still very prominent even when upgrading 11.0 NetScaler Gateway environments to 11.1. You may still have around 10-20% of your users get a blank white page after the upgrade. Yes even if you are already on X1 on 11.0 and keep the same X1 theme on 11.1 these users can be impacted. You’ll notice that base.css and rdx.js don’t want to respond which gives you a blank page:

If you try and type the the URLs for those files directly into a browser:

https://gw.yourdomain.com/vpn/js/rdx.js

or

https://gw.yourdomain.com/logon/themes/Default/css/base.css

you’ll notice it will show a Secure Connection Failed Message like this:

An error occurred during a connection to gw.yourdomain.com. SSL received a record with an incorrect Message Authentication Code. Error code: SSL_ERROR_BAD_MAC_READ
