503 Service Unavailable

I need help with my UCS server. installing mattermost and uninstalling it again. i am unable to get into my UCS admin page and same with all the other app like owncloud.

the 503 service unavailable page apppers.

Hi @tugava,

can you post some logging from apache? Something similar was already discussed at Openproject 503 Service Temporarily Unavailable after UCS update (although with a different app), there apparently a reboot fixed it.
