Failed to connect to api.hubapi.com port 443: Connection refused

[cmreinholz]

I'm getting the following error when trying to connect to this endpoint: https://api.hubapi.com/contacts/v1/contact/createOrUpdate/email/

Failed to connect to api.hubapi.com port 443: Connection refused

Any idea what would cause that? I tested the same endpoint/JSON using Postman and it worked fine.

I'm using PHP/cURL to connect. It's worked fine in the past.

Update: This issue eventually resolved itself on our servers, possibly a caching or propagation issue, but am unsure. Nothing changed from the programming side. Hope this resolves itself for you as well Chadr.

We are having the same issue using PHP/cURL to connect. It quit working 4 days ago after almost 6 months of working without a problem:

NOTE: This started the DAY that our SSL certificate was renewed. I assume it is related to this, but not sure why or how.

I haven't dug in real deep, but my impression is ours may have stopped around the same time.

I turned on SSL for our HubSpot hosted sites around the same time - that's the only thing I could think of that changed relative to Hubspot. But they seem like completely different things, so may be unrelated.

Hey @Chadr, I'm not sure of any reason you'd see that error. Do you have any more details or logs you can share with me so I can dig in?
