Qmc Not coming up after upgrade

[Gpoojith]

Recently we have upgraded Qlik Sense from Nov21 to Feb23, Installation was successful, and the services are running. When trying to access QMC, we see site can't be reached. 

We have the PostgreSQL 11 as standalone...

Trying to understand what the possible reason for the QMC could be not coming up...  

Any Leads please... For now, we don't have any Logs as the servers are restored back...

@Gpoojith  check to make sure all the necessary ports that Qlik Sense uses are available for the Qlik Sense services: https://help.qlik.com/en-US/sense-admin/February2023/Subsystems/DeployAdministerQSE/Content/Sense_De...
