Hi,

I tried to change server.xml in the WEB-INF folder but could not fix this and generally tried for hours finding the issue for this. I also found that changing the tomcat instance to tomcat10 instead of tomcat9 (as is shipped with cmdbuild4.0.0.sh although tomcat10 is “required”?) did not solve the issue

Anyone else having this issue?

#2

Is no one else having this issue? I don’t know what my local config / installations could have to do with it - i’m just installing from the .sh/.war file and this always happens

#3

Yes,
I have the exact same problem,
but I haven’t been able to fix it so far.
