Advanced Forwarding keeps failing (Nomorobo setup)

[jersey_weeds]

I am trying to follow the instructions here (https://nomorobo.com/phone/enable/4434392)  to setup nomorobo on my Xfinity VOIP landline and I keep getting greeted with the following message.  It appears as if the system is looking for previously set numbers for forwarding but hits an error at some point along the way.

First this...

Then this...

Any help would be appreciated. Thanks in advance!

Exactly the same error and problem in my end. I’ve been trying for 3 days. No luck when attempting to use this feature in the app or through chrome browser. Frustrating!
