Hi

I am getting this error massage on my Meraki 

I don't know why Meraki blocked the Umbrellas 

Any idea ?

Content filtering blocked URL

url https://doh.opendns.com/..., server 146.112.41.2:443, category Proxy Avoidance and Anonymizers

Because this method hides from Meraki the websites being accessed and you asked it to block anonymizers.

@PhilipDAth 

Should i allow or while list the doh.opendns.com ?

Thanks

That mostly depends on your requirements: should DNS over HTTPS (DoH) be blocked that'S using OpenDNS as its resolver?

Meraki actively blocking Cisco's own infrastructure is quite funny though. 😉

If you want to use the MX for content filtering and to be able to see what websites people have been too then block it.  If you don't care about either of these two you can allow it.
