In most recent I have been facing the similar challenge with the same Error. I am managing several tracker instances, and most of them are running at 2.30 (Everything is okay). 4 out of 6 tracker instances show the same error, only 2 was success. The challenge raises when I upgrade to 2.31 or 2.32 and even 2.33. All acts on the same way. Unfortunately, tomcat logs doesn’t capture any error and the Data Integrity seems to be okay. We have to depend on Console alone.
I am using PostgreSQL 10, and tomcat 8.5 . I added lines on server.xml
relaxedPathChars=“[]|”
relaxedQueryChars=“[]|{}^\`"<>”
It is still the same story. I will appreciate for you help. Should anyone be interested to access one of my dev system to examine the problem is welcome.
