Yes it is, "we plan to use our external VPS for handling the TLS termination". Edit: Ah I see you are just pointing out termination is on haproxy service not VPS. Thought you were implying it was terminating on pi, my apologies.

The VPS is running socat only and just doing tcp forwarding. There is a shared haproxy also run by their same host, sitting in front of the VPS and is handling the TLS. I encourage you to read the article fully. They probably should have said "VPS provider" instead of VPS for the TLS bit.

But it's plain text like you said in another comment after the haproxy, so two more plain text paths (with at least one going through the internet (vps->pi), not sure if haproxy->VPS is internal to the provider network (maybe)), so not ideal in my book
