Can't Access slrpnk.net

Recently I started being unable to access slrpnk.net via Thunder. I thought maybe the servers were just down, as I can still access lemmy.world through Thunder. Today I decided to check slrpnk.net in my browser just to check and it works fine (I'm positing this from it now), but I still can not access it through Thunder.

Does anyone else have this issue?
