+ - Ensure that port 22 (or other non-default port) is listed in allowed incoming connections. Run `azcmagent config list` on the Arc-enabled server in an elevated session. The ssh port (22) isn't set by default, so you must add it. This setting is used by other services, like admin center, so just add port 22 without deleting previously added ports.
