@samlimby closing this out as this is an issue with either ghcr.io, your docker setup, or a network firewall/proxy that is potentially rewriting your requests. Thanks @bmacer / @Rutwikdev.
When I run the the docker script in the terminal, I'm getting the below response (haven't included my API key - for obvious reasons - but I get the same response when I do input it).
Is this so...
