Hi everyone I'm using an Ubuntu server and I want to allow the access through any network in the world.

I configured the static ip address.
I have mapped the port 22-22 in the router configuration
I'm using the router ip address to perform an SSH connection

ssh user@router_ip -v

And here's the response:

OpenSSH_8.6p1, LibreSSL 3.3.6

`Authenticator provider $SSH_SK_PROVIDER did not resolve` seems like an issue on the mac client side. Are you actually trying to use FIDO/U2F authentication?

I had this same problem after connecting to a new network that had a different local gateway address than the previous network. I had a firewall rule that only allowed connections from a specific range of ip addresses like 192.168.0.0/24, but the new local network was a different ip range e.g. 10.0.0.1/16. Take a look at your firewall rules of ALLOW & DROP on the host, see if your local ip addresses are within the ALLOW range rule and not in the DROP rule.

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
