First of all thank you for reading my post and give yourself the time to help me.
After an update from 8.2 to 9.0 the application stopped working, did not connect the synchronization clients and started to throw an error on internal server.
I've done everything from reinstallation step by step to create a new server in parallel with the database plus the storage and even if it does not work.
Now I am not allowed to downgrade or anything. Just throw me in the web client this;
"Internal Server Error
The server has encountered an error and can not complete the request.
Please contact the server administrator if this error reappears multiple times. Please also include the technical details below.
More details can be seen in the server log.
Remote Address: 192.168.xxx.xxx
Request ID: SNKxuxUtdmgWdY + 9SNeg "
What information do I have to provide to receive some help?
Any information is of great help and I am eternally grateful.
I pay attention to your comments, a hug, best regards !!
