We have been using the Meraki MP API (Mega proxy?) for a while now, to pull in Meraki events into Splunk. It works great, up until about a week ago when it all stopped suddenly. Digging into it, it looks like the TLS certificate was updated for https://api-mp.meraki.com/, but since 'api-mp' is not listed in the cert's common name or alt names, validation fails. You can see the issue by browsing to https://api-mp.meraki.com/ with Chrome.
I've tried searching around for any evidence the MP API was deprecated or changed, but didn't find anything. Has anyone else seen this issue, found a solution, or raised with Cisco? Seems like someone stuffed up the certificate renewal, and missed a hostname..
