The error handler for 502/503 HTTP errors for services underneath of /univention/ says as fallback that "Univention Management Console Server" is not reachable and should be restarted. The Guardian APIs by default cause a 502/503 error when they are accessed via "http" or via the IP address. The error message is very misleading and should not mention UMC as fallback.
