Are you using the reverse proxy, that is recommended on Nextcloudâs page? Please note that URL scheme has changed, because it was not useable with HAProxy.
You need:
# Main websocket
ProxyPassMatch â/lool/(.*)/ws$â wss://127.0.0.1:9980/lool/$1/ws
Instead of:
Main websocket
ProxyPass /lool/ws wss://127.0.0.1:9980/lool/ws
I hope this helps.
