Expected behavior:
No Errors
Actual behavior:
- When I’m entering our Zammad URL, everything is working fine, but I noticed the 503 Error.
With a Apache log telling me:
**[Thu Oct 11 16:32:54.104903 2018] [proxy:warn] [pid 4287:tid 139648034662144] [client 172.30.30.1:44201] AH01144: No protocol handler was valid for the URL /ws (scheme 'ws'). If you are using a DSO version of mod_proxy, make sure the proxy submodules are included in the configuration using LoadModule.**
But I’v got already the required Modules enabled:
apache2ctl -M
