Nextcloud version: 22.214.171.124
Operating system and version: Ubuntu 18.04LTS
Apache Version 2.4.29
PHP version 7.2.19-0ubuntu0.18.04.1
The issue you are facing:
Unable to login to either NC webpage OR Linux Client (2.5.2git).
Client gets red banner “No connection to Nextcloud at https://cloud.mydomain.org, Server replied “503 Service Unavailable” to GET “https://cloud.mydomain.org/status.php” and NC webpage just shows " Service Unavailable The server is temporarily unable to service your request due to maintenance downtime or capacity problems. Please try again later.”
My Nextcloud install is running on a 2Gb KVM vps which took some kind of an outage early this morning, and once the node came back up, this malfunction began.
Each time I hit the NC webpage at https://cloud.mydomain.org I get the following errors from /var/log/apache2/error.log
[Sun Jul 28 17:37:40.126643 2019] [proxy:error] [pid 16096] (2)No such file or directory: AH02454: FCGI: attempt to connect to Unix domain socket /run/php/php7.2-fpm.nextcloud.sock (*) failed
[Sun Jul 28 17:37:40.126764 2019] [proxy_fcgi:error] [pid 16096] [client xx.xx.xx.xx:35996] AH01079: failed to make connection to backend: httpd-UDS
Upon checking the /run/php directory there is nothing in it…
Not sure what got bent when the vps went down unexpectedly…
Prior to this morning, the installation was working fine…
