I attempted this and I get an error saying https://monero.house is not a lemmy instance. Can replicate the issue above as well.
Could your phones DNS/VPN/Anti-Virus perhaps block the domain? I couldnt add the instance to Gerboa either in the beginning but when I last tried it suddenly worked.
I attempted turning off my Wireguard VPN, disconnecting from my wifi and using the mobile network. All same result.
EDIT: Mobile Network with simply monero.house worked. Bizarre.
That is very weird. I might seriously have to look into changing the domain name but monero.house is so cool :,(
Maybe monero.home, have both.
I just bought monero.town, together with a way better vps :) Let's see if I manage to migrate everything without issues.
Pretty good name. It is a shame that people have to use careless DNS services that cannot maintain a proper block list.
Solved: This was indeed the problem. I've been using NextDNS on my phone, and one of the threat lists was blocking Monero.House. I whitelisted the domain and was then able to login.
