If you cannot login to UMC, run the health script (umcServiceHealth) to verify the status of the services and resolve the issues.
Alternatively you can perform this tasks manually by verifying the services ic container, microfocus-umc-server, and postgresql.
Run the following commands to verify the status:
systemctl status docker-ic.service
systemctl status microfocus-umc-server.service
systemctl status postgresql.service
If the docker-ic service is inactive or has failed, run the following commands to restart the services:
systemctl restart docker.service
systemctl restart docker-ic.service
