Jira not accessible through browser after update.

[Mate Rados]

I have updated Jira from version 8.8.1 to version 8.20.12. Since then, I can no longer access Jira via the browser. The update went through without any problems and when I look at the Catalina log after the restart, I can't see any errors. In the Catalina log I see the message "Jira 8.20.12 build: 820012 started. You can now access Jira through your web browser. Plugins and caches are being initialised.". Unfortunately, I only get an HTTP 503 error in the browser. Jira is running internally and there is no proxy in between.
