Hi, when I try to connect from an

[paper wagon]

Are you using a reverse proxy?

[bright dome]

yes

[paper wagon]

Enable websockets

[bright dome]

how i can enable this

[paper wagon]

Good question

Let me guess what software you're using...

[bright dome]

i don't understand what is websocket and what i need to enable

[paper wagon]

Websocket is what HA uses

Old, well, ancient, reverse proxies don't enable them by default

If you're using NGINX then you have to turn that on

Google:
name of software websockets

[bright dome]

ok

[paper wagon]

Or... tell us what you're using and then we can help

[bright dome]

so has I understand i need to put on websockets in my nginx

[paper wagon]

Yes

Or move to a decent reverse proxy, like Traefik

[bright dome]

I think im gonna stay on my nginx because it's work for my website and other serveur but i take note about other reverse proxy

[paper wagon]

NGINX works, it's just old school

https://nginx.org/en/docs/http/websocket.html

[bright dome]

so ah block my proxy because he don't have websocket ?

[paper wagon]

I find Traefik so much better though, handles websockets natively, can update SSL certs, and more

thank for your help I will try to rework my nginx configuration
