A couple of hours ago, connections to my email host no longer went through - from Haiku and NetBSD, a couple different computers and revs. No upgrades or configuration changes, just stopped working, so I’m thinking there must have been some change on the other end.
DNS lookup goes OK. There will eventually be SSL protocol after the socket connection, but I don’t get to that point. Same code still works on on Linux, MacOS.
Is there some kind of new and improved TCP/IP protocol that they might have swapped in, at the hosting provider, that my Haiku implementation might be missing? I guess there’s someone at that address, because ping works, but from Haiku and NetBSD I can’t establish a connection to port 993. Times out.
