Hi, there,

I wanted to note a follow-up as I had this issue as well. Turns out, for me, it ended up being a problem in my Connection class. I had a scenario in my find_verified_user method that ended up calling reject_unauthorized_connection and killing the connection.

When I added a conditional block to account for a websocket request, all was good and this error no longer appears and, most importantly, reloading happened again :)

Thanks to all for the work on this hugely helpful gem!

I continue investigating this issue. So far I found out that websocket got disconnected due to ActionCable server restart: https://github.com/rails/rails/blob/main/actioncable/lib/action_cable/engine.rb#L91 But I'm not able to locate what's causing class unloading and restart. We use autoload_once_paths for app/channels folder so it seems not to be related. I'll appreciate any help. Very tricky issue.

I've faced the issue too. However, if you go with turbo_stream socket, it doesn't disconnect. I know it's not the best DX, but at least something 🫠

I've run into this issue as well. Using config.hotwire_livereload.reload_method = :turbo_stream fixes the disconnection issue. However, there's a related issue in that a second, quick subsequent edit will not execute a refresh/reload in the browser. Only after some cooldown period any subsequent edit will be reflected in the browser.

@pjg did you try setting up a config.hotwire_livereload.debounce_delay_ms = 300?

@mrfullset I tried, but it didn't change anything. I have plain CSS without any preprocessors, so this setting seems to not be applicable to me.

What I'm seeing is that for any change I make in a html or css file, I can see in server's logs it being broadcasted:

[ActionCable] Broadcasting to hotwire-livereload: "<turbo-stream action=\"replace\" target=\"hotwire-livereload\">...

but then it doesn't update on the browser side. And then after a short while I get another request for /cable (with "upgrade"):

Started GET "/cable" for 127.0.0.1 at 2024-05-24 17:17:48 +0200
Started GET "/cable" [WebSocket] for 127.0.0.1 at 2024-05-24 17:17:48 +0200
Successfully upgraded to WebSocket (REQUEST_METHOD: GET, HTTP_CONNECTION: upgrade, HTTP_UPGRADE: websocket)
Turbo::StreamsChannel is transmitting the subscription confirmation
Turbo::StreamsChannel is streaming from hotwire-livereload

And then the next file save will trigger a proper refresh.

Maybe I should file a new issue for this?

Same problem exists in Rails 7.2 beta 2.

After first file change and refresh it disconnects for a while until ActionCable reconnects again after 10 seconds:
