Anything else?

I am using AirVPN with a valid configuration file

This is not an issue but a config question..Please don't open issues for support requests.. that is what the Q&A is for.
Please look at your log, your container cannot resolve the DNS query.
Check your docker setup, try setting specific DNS, check the documentation for troubleshooting

[marvic2409]

I tried setting a specific DNS and it still gave the same error

[pkishino]

well, the initial dns lookup is failing. that lookup goes directly out based on whatever dns your network uses etc or that you specify. If this one fails then you need to check your network setup etc.
You could try to deploy a basic hello world container and see if nslookup fails as well.

Ah sorry, I was going to delete that reply, turns out restarting the docker service fixed the issue. Looks like it was an issue with the current docker service.
