i disabled v6 to keep things simpler. you must be using v4 to connect? if that's a personal relay you probably had the same 1984 bug effect you and it is not related to IP. its fixed now.

Yes, I'm running dual stack, and since your fix above everything is working. Still, in the long run it would be great if you could re-enable IPv6.
I realise this comes with an increased attack surface and several issues for the benefit of a relatively small number of users, but ultimately Nostr needs to be IPv6-friendly if we want resilience, global reach, personal relays running on mobile phones, and so on. IPv6 support is a necessary step for long-term sustainability.
Do you a repo (or set of repos) with your settings / customisations / plugins / etc to strfy somewhe?; It would be interesting to understand what you are doing around NIP-56, WoT, etc.
i still use nostr-sdk 0.12.1 :)
people would be shocked by my tech and coding style :)
Whatever you are doing, I dount Its worse than some of the code that I'm making public out there (I'm shameless) 🤣. Not trying to pressure you to OSS it though. But for small time relay devs like me it would be interesting to get an idea on how the big relays are handling stuff.
