Hi everyone,

I’m using Anthias on a Raspberry Pi to display an internal webpage.  
This page is served over **HTTPS** and uses a **self-signed certificate** (or one issued by an internal CA).

Here’s what I’ve tried so far:

- Placed the certificate in `/usr/local/share/ca-certificates/` and `/etc/ssl/certs/`

- Ran `sudo update-ca-certificates` to update the system certificate store

- Tested with `curl https://my-site` → works fine, no SSL errors

So the operating system (Raspberry Pi OS) does trust the certificate.

**Problem:**  
In Anthias, however, the page is still **not displayed** – it’s simply skipped without any error message.

My assumption is that Anthias uses its own browser/renderer which does not rely on the system’s certificate store and blocks self-signed certificates by default.

**Questions:**

- Is there any way to add a custom root certificate to Anthias?

- Which browser engine does Anthias use internally (Chromium, uzbl, something else), and can it be configured?

- If not: Is there any plan to support self-signed certificates or private CAs in the future?

Thanks for any help!

@Flix, certificates should be included in Docker containers as well. We currently have a utility for that.

Please refer to this documentation about [Installing trusted self-signed certificates](https://github.com/Screenly/Anthias/tree/master/docs#installing-trusted-self-signed-certificates).

Please let me know if you’re still having issues after following the guide.

Hello,

Thanks for your reply. I added the certificate as per the instructions. It was added successfully, but accessing the website with Anthias still doesn’t work; it simply overrides the page. Using curl [https://my-site](https://my-site), it works perfectly.
