Synology’s build in reverse proxy is really nginx under the hood. Everything was working fine up until the last upgrade I did.
Now all websocket(wss:// and ws://) requests get a 400 Bad Request response.
I see the nginx config instructions in the docs, and looking at the nginx config, mine is the same except for the dhparam part.
Question is, what’s the actual change needed between releases to get websockets working again? ie. Not config nginx from scratch.
