Docker 403 Error (Port?)

Hello guys,

I have a problem with my website. It worked great until a error 403 displayed when I tried to view my website.

I logged into Plesk and it says that the Homepage Docker is not running anymore.
When I try to start it it says:

{“message”:“driver failed programming external connectivity on endpoint Homepage (**********************************************): Error starting userland proxy: listen tcp 0.0.0.0:80: bind: address already in use”}

I tried to stop ngnix (sudo nginx -s stop). After that the Homepage starts again but I still can’t access it. I get a connection error.

Do you know what else I could do? Did you face the same problem?

Also got this when I tried to push it:
