Lightspeed, Wise POS, Stripe, and Comcast issues

@Comcast_Shan​ Thank you.  I have sent a direct message today Fri 8/5/22.

Did you ever get a satisfactory response to this?  We are in the SAME boat!!!  Thanks!

When we connect our Verifone 400 payment terminals to our Lightspeed application.  You enter a "pairing" process.  On the terminal, you get 3 random words that you have to type into the Lightspeed app (on the browser).  If I do this while having the browser "dev tools" open, I can see a lot of positive communication to the internet.  The terminal shows up in the background of the Lightspeed app.

But...

Then there is an attempt to contact this URL:

https://[ip-address].[random-string].device.stripe-terminal-local-reader.net:4443/protojsonservice/JackRabbitService

For security, I am not showing the "real values" for [ip-address] and [random-string], but they look similar to:
[ip-address] = 192-168-1-34
[random-string] = xmcheakdfovelsprhtns

The first communication that fails is a FETCH/OPTIONS, and then a POST.
These communications fail due to a "CORS Failure".

When this happens, the terminal disappears from Lightspeed.  The terminal says that is paired successfully, but Lightspeed says there was a communication failure.

I am certain that what is "trying" to happen is that the browser is trying to "talk" to the terminal at its [ip-address].  But for some reason the DNS is failing with a CORS issue.

These terminals have been working fine for 2+ years with no issues, and then suddenly this month they started failing.  Nothing has changed on our network in the store.

But our payment terminals have been offline for over a week - meaning we have to key in the credit card information directly into the Lightspeed application - very laborious and cumbersome!

Lightspeed has told us that they have many customers that have "SecurityEdge" from comcast and this is what is causing the problem.  We have requested SecurityEdge to be turned off for our account to see if that is the issue.  We were told that it was turned off, but will take 24-48 hrs to take effect.
