PR_CONNECT_RESET_ERROR when i use cloudflare proxy

I have two domains, they are configured pretty well, the CNAME are Herokus, I follow the documentation with ACM certifiactes, when i activate the proxy in Cloudflare, i lose the access to the domains,

what I have as configuration:
1- Cloudflare Proxy is activated
2- SSL are from Heroku ACM
3- Use always HTTPS is Activated
4- SSL/TLS encryption mode is Full (strict)


Any idea about the error and how i can fix it

Hi :slight_smile:

It seems to be an error coming from Heroku. Did you contact them?

Check the details how to configure here:

Take care!

yeah i did, they respond with a weird answer, may Cloudflare confirm,
they said that Cloudflare not supporting the ACM certificates from Heroku,
I have to generate new ones from Cloudflare and upload them to Heroku SNI

It works but it’s very intersting how they drop the ACM support without mentioning it in the docs both in Heroku or Cloudflare

Thank you anyway

Indeed, when you are using Cloudflare you need always the edge certificate at our side.

Check our encryption modes options here: Encryption modes · Cloudflare SSL/TLS docs

Take care!
