502 Bad Gateway
Posted: Wed Jun 20, 2018 9:44 pm
Hello! There was a following problem, on several servers with the VestaCP panel.
The panel itself works, we can use console commands to work with it, but the web interface does not work, the logs have the following errors:
The file /var/run/vesta-php.sock present
With ports there are no problems, the connection does not deviate:
What could be the problem? It manifests itself massively, on several servers, with different operating systems.
Restarting the panel is a temporary solution, after which the web interface drops again.
More detailed logs:
We restart service vesta and after that the web interface down, after a certain time.
At the same time, there is free RAM, 1 GB is available.
The panel itself works, we can use console commands to work with it, but the web interface does not work, the logs have the following errors:
