Meraki & Plex

[Tal]

I have a Meraki MR56 connected to MX75. The MX75 is connected to my ISPs modem/switch.
On one of my servers I'm running Plex media server and a client, connected to the same SSID can't reach the server.
On the same ISP modem/switch I have a google mesh.
If the Plex Server and the Plex Client are connected to the SSID of the google mesh - everything is working.
Any idea how to resolve this on the Meraki?
Thanks

Just to make sure . When both the client and the server are on MR56 it's not working , but when using an other AP ( google mesh ) it's working ?

I would make sure that client to client traffic is set to allowed under the firewall page. See below

Is your mr ssid in bridge mode?

You ssid has any fw rules?

no FW rules at all.
