Brand new installation of Jira Align and when we access Jira Align directly we are able to login with the default username / password. If we stand up an Apache reverse Proxy that is only modifying the port (IIS is responding on port 8080 and Apache is responding on port 80), We can no longer login. No error message appears, it just redirects back to the logon page.
There are no error messages and nothing in the logs. The Login does not appear in the Align logs whether it succeeded or failed.
