Every time I try to use Ipv6, I run into dozens of weird issues and bugs and my selfhosted stuff becomes unusable/unreliable.
I don’t know where the issue exactly lies in the chain of networking, but it sure is annoying as a motherfucker to debug. As far as I can tell none of my stuff is the problem and the issue lies either with my ISP or VPS provider.
For now, I removed the AAAA entries and suddenly everything works without any hiccups. Wake me up when those issues are solved… maybe in 10 or 20 years…
