Hello:
I am wondering if anyone has any advise on how I can do to stop google from requesting CHAPTA on every search. Issue popped up once I setup /48 tunnel. My guess is the previous user of this subnet was little more dubious with their usage. I've had it up for about a week now so I was hoping the issue would self resolve but not had much luck.

We have been seeing this at work on IPv4 connections too. I realize this doesn't solve your issue, but it's not just you.
Glad to hear I am not alone. As a side note the issue does not seem to occur on my IPv4 only configured devices.
