Hi @casainho , When you see this network indicator, it means you cannot connect to the AppFlowy server using WebSocket, which is required for real-time collaborative editing. May I ask where you’re accessing AppFlowy from? There might be a network block causing this issue.

Thanks!! I am hosting on a Linux PC and using Nginx Proxy Manager (NPM). Everything were working before, I think the only change were or with the PC app or on the AppFlowy-Cloud.

My relevant configurations about WebSocket on NPM:

And on advanced tab:

location / {
proxy_pass http://192.168.x.x:8800;
}

location /api/websocket {
    proxy_pass http://192.168.x.x:8800;

    proxy_set_header Host $host;

    proxy_http_version 1.1;
    proxy_set_header Upgrade $http_upgrade;
    proxy_set_header Connection "upgrade";
}

@casainho Have you try restart appflowy? If yes,did it work?

Same issue here, I updated my Appflowy desktop version to 0.9.5, and update my server to 0.9.64. (Using Windows 10 + Docker)

I tried restart & reinstall desktop app and server, but didn't work for me.

I downgraded my appflowy desktop to 0.9.4, and it works fine.
