I managed to find the issue.
It was an IPv6 default-route issue on the remote end.
The remote host uses a DNS name with dual-stack, and its network router had a problem with the IPv6 default route. So, the host was receiving SNMP requests, but some replies were on limbo.
After fixing the default-route, it is now connected with no more issues.
Btw, it is a Mikrotik router, but I wasn't monitoring its routes.
