Troubleshooting Endless Loop of Web App Login when UMS Installed with Non-default Port

After installing or upgrading to the newest version of IGEL UMS (Universal Management Suite), version 12.08.100 with a non-default port (e.g. 443), you might find that logging in to the IGEL UMS Web App leads to an endless browser loop.

Problem

The configuration file of the wums-app is misconfigured, which activates the fallback to the default port.

Solution

Open the file {installation.path}/rmguiserver/webapps/wums-app/WEB-INF/classes/config/application-embedded.yml

Move the config for auth-service port from igel.wums to igel.client

The file should now have a section like this:

client:
    permission-service:
      port: ${igel.embedded.tomcat.port}
    license-service:
      port: ${igel.embedded.tomcat.port}
    auth-service:
      port: ${igel.embedded.tomcat.port}

Restart the UMS Service.
