Can you run the following and let me know if you get an output, it's a command to perform a DNS query. dig registry-1.docker.io

Thanks, can you set the DNS server to not go via your Pi-Hole and try again? Set the DNS back to your default DNS address, for example, 192.168.1.1, 8.8.8.8

This way we can eliminate Pi-Hole being an issue.

[JJandPenguin]

so it was pihole and tysm for helping me and sorry for dragging you through this

[Nick-Portainer]

That's okay! It's why I am here. Glad we got there in the end

[JJandPenguin]

one last question how do i change the port of my running portainer container or delete it?

[Nick-Portainer]

Ports can be changed by changing the mapping for example docker run -d -p 8095:9443.... (This is for a new container) More information on the networking can be found here - https://docs.docker.com/network/

If you want to delete your container you can do docker rm <container name> but it will need to be stopped first via docker stop <container name> See here for more details - https://docs.docker.com/engine/reference/commandline/rm/ - https://docs.docker.com/engine/reference/commandline/stop/
