I recently encountered an issue where two Macs were disconnected despite both having their firewalls turned off. The problem persisted until I reopened the control panel and restarted the connection. Upon further investigation, I found that the issue was likely caused by a firewall misconfiguration. To resolve this issue, I recommend ensuring that the firewalls on both Macs are properly configured and not interfering with each other. Additionally, I suggest restarting the network connection and reopening the control panel to ensure a stable connection.
