My YunoHost server
Hardware: Root Server by Netcup
YunoHost version: 4.3.6.2 (stable).
I have access to my server : Through SSH | through the webadmin | VNC
Are you in a special context or did you perform some particular tweaking on your YunoHost instance ? : no
Misskey is, except known bugs in 12.102.1, running without problems.
Today I added an IPv6 address to my server / Yunohost and everything works smooth, installing AdGuard also.
But in Misskey messages were delayed and not delivered now.
After switching back to IPv4 only, messages were delivered properly again.
Any hint why this happens and how to change this behavior?
