Bug report
After updating to 2.1, the WebUI isn't reachable anymore via IPv6. If I force the use of legacy IPv4 I can connect. On 2.0.16 IPv6 worked fine.
Steps to reproduce
The hostname of my Hyperion server is vesta. When I open a browser and navigate to http://vesta:8090/ I get a connection closed error. If I manually put in the IPv4 address (http://192.168.1.10:8090/) then the connection works. If I manually put in the IPv6 address (http://[2a02:xxxx:xxxx:xxxx:xxxx:xxxx:xxxx:xxxx]:8090/) then I again get the connection closed error.
What is expected?
Both IPv6 and IPv4 should work. When I try to connect by hostname, IPv6 gets priority over legacy IPv4, so this is breaking not just the webUI, but also the Hyperion integration of my Home Assistant system.
What is actually happening?
When I try a telnet to port 8090, on IPv4 i get this:
vesta$ telnet 192.168.1.10 8090
Trying 192.168.1.10...
Connected to 192.168.1.10.
Escape character is '^]'.
When I try IPv6 it connects and immediately closes the connection:
vesta$ telnet 2a02:xxxx:xxxx:xxxx:xxxx:xxxx:xxxx:xxxx 8090
Trying 2a02:xxxx:xxxx:xxxx:xxxx:xxxx:xxxx:xxxx...
Connected to 2a02:xxxx:xxxx:xxxx:xxxx:xxxx:xxxx:xxxx.
Escape character is '^]'.
Connection closed by foreign host.
Oddly enough, if I try to connect to localhost on vesta itself, via IPv6, it works:
vesta$ telnet localhost 8090
Trying ::1...
Connected to localhost.
Escape character is '^]'.
ss shows the system is listening on both IPv6 and IPv4:
vesta$ sudo ss -ntpl | grep :8090
LISTEN 0 50 *:8090 *:* users:(("hyperiond",pid=437,fd=29))
This is the same as on 2.0.16, where both worked fine.
