Similar problem.

TIA Portal Multiuser Server V15.1 Administration tool shows error "The server is not available" while opening "History" tab of certain project.

In the same time there is no such a problem for other projects on the server. It is also possible to download latest changes (refresh) for that problematic project when its local session is opened in TIA Portal.

So the error is misleading because server seems to be OK.

Action taken so far:

• Server restart
• Double checked tat the project is unlocked
• "Alerts" tab checked: Nothing relevant
  

Are you familiar with this problem? Any ideas how to fix it?

Split from Multiuser Server 15.1 : server not available.

Hi,

Did you find some solution about this issue? I have same trouble with Tia project server multiuser v19

Unfortuantely not. For one project on our Multiuser server problem still persists.

Did you find a reason of the problem with/on your server?
