Jenkins docker container error digitalocean droplet

Docker Hub
1

Inside our droplet cloud server we got docker containers running we recently ran out of space in our droplet and got additional volume after the server restart we have encountered an error. All of our containers were working except jenkins container The status of the container is up and when we check the status of the container on portainer it looks like it is running without issues

But when we try to access our jenkins UI it throws “502 bad gateway openresty” error and we cannot understand why

our jenkins container is using docker in docker principle

any reasons why this might be happening ? and how can we fix it?

here is my jenkins container log
