Transdroid doesn't work when overrideing server name with a `CNAME` record on local network

[PHLAK]

I have my server set up in Transdroid via a domain name. This domain name is configured in Cloudflare as a CNAME record (resolving the IP address of another domain name) and everything works correctly when I'm connecting from outside of my home network.

On my local network, I attempted to override the CNAME entry for local DNS on my home router (to keep traffic internal) and when I do, Transdroid fails to connect. This CNAME redirect works fine from any browser on my PC.

If I change the local CNAME override to an A record Transdroid works.

Hmm while there isn't anything specific that Transdroid does with DNS lookup, it might be because it's still using the ancient Apache HTTP client API offered by the Android platform and which has for many years been deprecated. So while I don't think there is a specific bug in Transdroid, it does show (again) that the codebase is aging and in dire need of a refresh. I am open to doing this work but hope to consolidate the supported clients a bit to a smaller list.
