Anybody else have this happen? I'm using cloud version. I spent a bunch of time making sure that all of my APs, SMs and cnPilots were onboarded and showed online. Added new mgmt vlans per location and everything was working great. I have made no network changes, but suddenly the SMs show offline at ALL locations. APs show online and so do cnPilot routers. I can't figure out why suddenly they each show "resolving" under the cnMaestro tab under configuration. They all were connected before.
@Wanda, from one of the device user interfaces, can you using the PING test to see if you can ping https://cloud.cambiumnetworks.com? Can you perform a DNS lookup? Are there any issues with the DNS IP configuration on the devices that is preventing them from resolving the URL?
it does seem to be a DNS issue because from the devices I can ping 8.8.8.8, but I can not ping google.com or cloud.cambiumnetworks.com. Yet, even if I use 8.8.8.8 as primary DNS I still can't ping google.com.
Before 6 days ago, this wasn't an issue. I have tried a few primary DNS servers and still have the same issue.
and when I do a dns lookup it says "no results"
@Wanda, so the problem is only with SMs, correct? What product line is this, PMP or ePMP? What software version is running on the SMs and their parent APs?
