Apache returning too many redirects

[Nathan Meek]

I could access our JIRA installation a couple minutes ago. Changed the User Directory order, logged out, went to log back in and am now experiencing a "Too many redirects" error on both the default port (not touched by Apache) and port 80 (which is reverse proxied from port 8081).

Check if this is the case? See https://confluence.atlassian.com/display/JIRA/Troubleshooting+Apache

Too many redirects

Both Tomcat & Apache are redirecting, when only one should be. Disable redirection in Tomcat (revert any changes as in Running JIRA over SSL or HTTPS) and check that there is only one redirection in Apache.

General Problems

1. Clear the browser cache and try again.
2. Ensure that JIRA works as expected when running directly from Tomcat and bypassing Apache. For example, accessing http://jiraserver:8080 instead of http://jira.atlassian.com.
3. Increase the LogLevel for Apache to debug and restart it.
4. Attempt to access JIRA and check the Apache Log Files for any errors.
5. Raise a question on Atlassian Answers for assistance.
