Hi John, sorry to hear that you are getting that error while running your migration.
The cURL error 6 indicates that there might be a problem with the DNS associated with that particular website and our team was able to do some additional digging to help figure this out.
From what we were able to find, there seem to be some problems with the DNS for joyndwood.com and the IP information for that domain has not propagated to Google DNS, which prevents domain lookups with cURL in Cloud WordPress from functioning as expected.
DNS propagation can take some time, but I think you should contact your hosting provider just to make sure there aren’t any problems with the DNS information reported by their nameservers for your domain.
I hope this helps you get the migrations working properly John and please let us know if there is anything else that we can do to help!
