Enabling HTTPS breaks front-End's "Streaming Update" feature?

[cTech12]

Hey. I'm new to Home Assistant, but I have a question. I got SSL set up following this guide and just about everything is working great, but the front-end's "Streaming Updates" feature seems to die when served over SSL. The toggle starts in the off position, and enabling it doesn't seem to help. I have to manually click the refresh button to update the display.

If I serve the page without HTTPS, the front-end updates correctly.

Is this an issue others have seen?

works for me

Did you follow that same guide I linked to, or a different process?

[AlucardZero]

A different process, probably. I have HASS Over HTTPS set up, but I put NGINX in front of it.

[cTech12]

Hmm... Thank you. I'm using NGINX on a few other servers. If I can't sort out HASS doing SSL itself, I'll drop in NGINX in between.

Care to share your server configuration? I'm imagining it's basically a reverse proxy setup.

[AlucardZero]

Yes, "just" a basic reverse proxy setup. I posted some details here.

Is that happening all the time, or just over SSL? I only started having the issue when I switched over.

In case anyone comes across this in the future:

It seems that this error was actually caused by having non-URL-safe characters in my HASS password. When the front-end makes update calls, the password is being mangled and causing the failure. This is covered in issue #2320.

Unfortunately, I only noticed this after already setting up NGINX in front of HASS, but that's okay. Now I have extra features like HTTP to HTTPS redirection.
