@firstname.lastname@example.org Something is off with your server. I have a lot of trouble with the official twtxt client’s Python AsyncIO to fetch your feed for a few days. Always get a
ServerTimeoutError('Connection timeout to host https://yarn.zn80.net/user/carsten/twtxt.txt'). It turns out, both IPv4 and IPv6 addresses are resolved and the v6 one is preferred. However, connecting via v6 (
2606:54c0:5540:18::14:2a4) fails and an attempt with v4 (
184.108.40.206) is not made at all, the whole thing just aborts. :-( (I believe this is an error with
curl, on the other hand does fall back to v4 automatically and then suceeds in getting your feed. It also attempts v6 first if I interpret the verbose output correctly. I temporarily monkey-patched the
twtxt client to force IPv4 usage and was able to download your feed.
Now the really weird thing: Your firewall seems to block ICMP for v4, but not for v6.
ping4 returns nothing,
ping6 happily replies back. What the hell?
