Connecting to a websocket server hosted on render

So I’m having a problem connecting to my websocket server hosted on
The server is a dead simple node.js websocket server. My client would be an ESP32.
On the ESP32 side, i need some CA and CERT files from render in order to connect to it but i see that
render can not give me the CA for my server and self signed CA is not working.


ESP32 websocket client —> Node.js websocket server

How can i solve this problem?

Hi there,

If you need complete control over your TLS certificates, you’ll need to put a proxy you control in place in front of your Render service.

If this is something you’d find useful out of the box from Render, I’d encourage you to submit a feature request at It helps to include as much context as possible about your use case, the problem you’re looking to solve, and how you’re getting around it today to help us develop the best possible solution.

I see this existing feature request you could also simply give an up vote for

We rely heavily on customer feedback as a part of our planning and product roadmap process, so capturing interest on the feature request page is very helpful.
