While Meraki appliances have traditionally relied on UDP port 7351 for cloud communication and TCP ports 80 and 443 for backup communications, with MG 3.0 we are beginning a transition to using TCP port 443 as the primary means for cloud connectivity. In order to ensure proper connectivity to the Meraki cloud after this upgrade, please ensure that all “Meraki cloud communication” traffic specified in the Help > Firewall Info page is allowed through any firewalls or security filtering devices that may be deployed upstream of your Meraki appliances. These requirements have been updated on Nov 2022, so it’s important that you review them.
