Hello!
My team has had a test site setup using a reverse proxy for a few months now. Noticed near the end of October than it stopped working.
Errors are SSL handshake related. I believe it’s because the hubspot domain we’re proxying to doesn’t have our domain on the certificate.
Anyone else running into this? I’ve tried emailing hubspot support and not gotten a response.
Here is the output from openssl client
