Hi @Moben,
This problem can be for some reasons, make this check:
- Owner of identityiq folder and subfolders (must be the account you launch tomcat with)
- Owner and permission of tomcat folder
- If the name of tomcat folder is changed, you must update the iiq configuration files
- Check how tomcat process you have with ps aux | grep -i tomcat for example. Stop all process and start tomcat again
PS Before new installation, do you stop the old tomcat instance? Also, if you change the name of folder you need to change the /etc/systemd/system/tomcat.service
