MX is offline but Switches and Access Point are Online In Dashboard

[Sapkota_A]

Hi i can see my uplink and MX status is down but MS and MR are online from the Dashboard. But i am able to ping the WAN ip of ISP from my end machine. 

Any idea what might be the reason behind this ?

Do the switches and AP's actually use the MX as gateway towards the Meraki Cloud?

Is there a firewall in front of the MX that is blocking certain ports?

You could also locally login to the MX and see what error it has.

Yes switches and AP are using MX as a gateway towards Meraki Cloud. Also no upstream firewall is in place blocking MX. As i cant login locally its an remote site.

What does the local status page of the MX say is the issue?

RCA for this issue was: Site is having 2 ISP terminated on the MX. Due to billing issue wan1 was having an bandwidth constraint due to which it was not failover to backup link leading flapping in the network gears. Usually when there is an billing issue circuit should be down but in this case it wasn't so. 

Hope this helps.

Thanks,
