We are seeing failures on IPv6 Address found, IPv4 Expected errors coming from https://ssl.gstatic.com/accounts/o/682094929-postmessagerelay.js
What does this mean
Answer by Diana D. ·
It means your test is setup for IPv4 only, and some of the nodes you have configured in your test are IPv4 and Ipv6 (mixed) so your test is generating the error "IPv6 address found, IPv4 expected".
It would be recommended to change the IP setting for the test to IPv4/IPv6 mixed mode so it will test without issue. You can modify IP settings under the Admin> Add/Edit Backbone Tests link in the portal.
