Hi Guys I have 4 different networks with different MR Aps Network 1 mostly MR53E, few MR36 and to MR76 (all wired) Network 2 only MR53E (one wired, 4 are using mesh) Network 3 only MR53E (all wired) Network 4 mostly MR53E, 4 MR46E and 2 MR76 (all wired except one MR76 and one MR53E) All on 28.5 Firmware Last Week i scheduled an update on Network 2 to 28.6 (its a little one,so perfect for testing), everything worked fin so i upgraded Network 2 an 3 to 28.6 and also everythings fine But i'm unable to upgrade to 28.6 on Network 4 because i'm getting this error message "Firmware Upgrade failed due to the following node_groups: Althengstett. Firmware Versions MR 28 and MX 16 require nodes to be able to contact Meraki's Device to Cloud Connectivity service over TCP port 443. One or more of your Meraki devices are unable to communicate with these new servers. For more information about this upcoming change and how to resolve the connectivity issue, please go to https://documentation.meraki.com/General_Administration/Cross-Platform_Content/Meraki_Device_to_Cloud_Connectivity_-_FIPS" Any ideas or hints what i can do? on this Network 28.5 is already running so there shouldnt be block anything Thank you so far
