Firefox Version 50.1.0 - Black screen

[dionatan]

Hi

That's our first week using TSPlus. We got a problem with Mozilla Firefox version 50.1.0. After de logon screen, page becomes black and nothing happen.

Any tips about how to solve this problem?

Which version of TSplus? And which Windows version?

Hello,

Open an admin tool, and click on "Web Management Tool". make sure all features are set to green. if not, click on "Restart Web Server". If the server won't start, make sure you have not installed another web server or application that would be using the TCP port 80 and/or 443 (Skype and Teamviewer for example). One easy test to do is to change the port of your webserver and restart the server again. A faq regarding this subject is available here : http://support.tsplus.net/kb/faq.php?id=6

Open a browser on the server, type in the address http:// 127.0.0.2 and open a connection using the RemoteApp or html5 mode. You should be able to open a session with a local or domain account.

If it still wont connect, uninstall java and delete the java folder located in C:\Program Files x86\ and C:\ProgramData (this is a hidden folder) then reinstall java 64 bits on the server.

Olivier probably covered everything, but just in case:
Have you installed the December update rollup? https://support.microsoft.com/en-us/kb/3205401
There was a bug since May/June rollup, which did make all RDP connections unstable. That was fixed in December.

HTML5 works on Google Chrome and Edge, i'll try to install windows updates.

If i correctly remember you was using KEMP load balancer which is known for incompatibility with FireFox's Websockets when used with SSL.
And so far I know, they have never fixed it.
I assume Kemp tampers Websockets traffic, possibly reestablish new connection with different parameters and FF does't seem to like that.
So the best you can do, either stop to use FireFox or Kemp.

Hello,

Running the latest TSplus version on our vps in the cloud with Windows 2012 R2.
Connecting with Firefox 50.1.x (HTML5) to our 2012 R2 server is working great, so no problem at all.

Best regards
