Hello, it was a mistake in the proxy, thanks for reporting. Also, I'm switching to host only one relay, every url are pointing to wss://relay.nmail.li
Thanks! I noticed that the new domain resolves to IPv6 as well. IPv4 works fine, IPv6 seems to fail:
```
$ curl -v6 wss://relay.nmail.li
...
* TLSv1.3 (OUT), TLS alert, decode error (562):
* TLS connect error: error:0A000126:SSL routines::unexpected eof while reading
```
```
$ curl -v6 wss://relay.nmail.li
...
* TLSv1.3 (OUT), TLS alert, decode error (562):
* TLS connect error: error:0A000126:SSL routines::unexpected eof while reading
```
