Our eyeball customers all of a sudden can no longer reach their CBS all access content. Inspection of the network connections now show a 403 error when trying to post to https://cbsi.live.ott.irdeto.com/widevine/getlicense   
code: 100214
message: "The request originated from ip address 196.53.97.0 which is not included in the JWT ips claim."

I'm going to assume that they randomly started geolocating differently. Wonder if it's either CBS, or irdeto that can help us resolve our IP block 196.53.96.0/22 issues.
