Hi guys,

Thanks for stepping in (and apologies for the late reply, things have been a lot hectic around here lately).

Ultimately the issue was that the public subnets on the accepter VPC automatically inherit the PCX connection, but that does not hold true for the private subnets; after explicitly adding the PCX connection to the private subnets our issue was solved.

You may consider adding this extra bit of information to the wiki article 🙂
