Dear Community,

Meraki MX keep sending request through the back-end, as we try to pcap on upstream device still see the traffic request same src, dst port to VPN Registry Server, you maybe need to change session setting on upstream device like UDP discard, etc as MX use UDP port 9350-9351 to VPN Registry Server.

Thanks, BR,

Thank you so much @Inderdeep,
We have been try those reboot, yeah it is working.
But we notices, log VPN connect to registry retry only two request. If MX try to 2 request fail to VPN registry it will not retry again and show VPN registry disconnected. Any other solutions instead of reboot MX or upstream devices?

Thanks,

Dear Community,

The problem is the upstream device, due MX still keep retry to connect to VPN registry(dst UDP 9350-9351) every 10s so upstream device still keep that session alive from MX.
The restart MX or modem is force to restart source port that MX uses to connect to VPN registry, it is not a good solutions if under production and VPN concentrator deployment.

So the solution should be check, fix on the upstream device such upstream Firewall, or ISP.

Thanks, BR,
