Can't connecto to IPv6 only server

[DaCookie4u]

Not sure, if this is a problem with DSub. My Subsonic server is IPv6 only and I can use my Mobile to connect to the Subsonic webfrontend without problems. DSub unfortunately can't connect though.

I installed the latest DSub release 5.5.3 and my Subsonic server is 6.1.6 runs on docker behind an HTTPS proxy. It ran flawlessly on an IPv4 setup.

Error message says:

Connection failure. Resource not found. Please check the server address.

Any ideas?

i can connect to IPv6-only servers via their hostnames or by writing the IP in this format: http://[2001:db8::69]. so it is possible in principle.
