Question Panel error ?

[AlexJoker13]

Hello, good afternoon / night to all, recently I tried to update to the latest version of plesk, when I tried to do it I got an error in the log.
And now I can not access the panel because it gives me an error "Server Error 502 Bad Gateway"
I have an Ubuntu operating system 16.04. Here I leave a capture of the error that I get when trying to repair the plesk from the console.

Try to fix it with

# plesk installer --select-release-current --reinstall-patch --upgrade-installed-components
# plesk repair installation

I think you need to reinstall the previous patch
