Plex Media Server suddenly not available through app.plex.tv, not remote, not local

You know what? There is only one server, one ip adress, i have no idea where the second flix is coming from. I deleted this server in the devices tab, unfortunately the one that is not available is the right one. I think i have the same problem as this guy here: Can't access remotely since Plex.tv API update - authentication server

how can i send you logs? i can login with ssh, plex service is running, but no way to get there with any app or browser.
