upgrade to November 2022 Problem

[kgalai]

Hi 

We have upgraded to the November 2022 version of Qlik Sense on 8 November 2022.

When trying to connect today we faced several problems related to the connectivity to licences servers ("message":"failed retrieve central node info from QRS)

Kindly note that we can't see connectors and the message of the attached file (bug1) is displayed when when open the load script

Hello @kgalai , 

The error you are seeing could be related to TLS/SSL and Ciphers, please review the following:

You mention issues contacting the license server. Do you see errors in the Repository > Trace > System logs?
If you are still having issues contacting the license server please refer to the following:

Hi Jay,

Thank you for your response,. I confirm that its related to TLS/SSL protocoles,. I've been in contact with Qlik support , they recommend me to download  IISCrypto.exe  , I fixed the issue by running the program and restarting the server . Now we have no more the "unknow error" message and data connexions are displayed on the load script.

Regards,

Karim
