Getting internal server 500 error after setting up knime server on our machine

Hi Team,

I did the setup on our on premises server and after login in thru web portal its showing 500" something went wrong wrong"
An internal server error has occurred: Illegal character in authority at index 8: https://knime-server hosted site , localhost:8080/knime/rest/v4/repository/

For assistance please contact your server administrator. More information about the error can be found in the server’s log files.

Also guide me where I can see server logs generated ? In our tomcat logs:
