Dears,
after installing Sentry on-premise I faced 502 Bad Gateway Issues it tries again and again and if I need to fix it I must run docker-compose down then docker-compose up -d
and after that show me an error in Nginx container
My best guess here is lack of RAM. Might be too many workers and threads but that boils down to lack of RAM.
But due to the limited amount of info we have here it is hard to say.
