We are running metabase as JVM JAR file.
Just upgrade metabase from v0.33 to v0.42 and after the server reboot, we can see all data is present, but missing Collections data.
There are no graphs displaying and missing personal collection.
Any leads are appreciated.

Thank you.

Hi @ishan1
There must be other errors showing in the log.
And I'm sure there must have been errors showing during the upgrade.

Issue resolved.
Requests were getting blocked at WAF after metabase upgrade.
