I recently did server reinstall and started my hubzilla from scratch and then restored my channel from backup file.
I noticed that when I was trying to register new account I couldn't use my domain. I use selfhosting.rocks for Hubzilla and Zap.
I was able to do it before (I think it was still in 3-series)
If I change the ending from rocks to .com or .net it doesn't complain.
Luckily I have also .com addresses so I was able to register and then restore.
Is there set of domain suffixes that are allowed, or is the problem somewhere else?
This is not so huge problem for me, because I'm the only user here and I was able to register with another email.
