What's Wrong?

[P0] Highly destructive of any remote workflow, entirely destroys feature.

As of yesterday, remote control started sessions suddenly disconnect for no apparent reason. When sending a new message its just showing the following toast: „An unknown network error has occurred. Please try again“.
The interactive sessions are shown in the Archived Section! Despite never being archived, neither on the iphone App nor the TUI.

What Should Happen?

At the very last there HAS to be a command/option to restart or retry the connection from the phone. There are so many issues like this one still that would all benefit from this

Error Messages/Logs

Failed to send message.

This evening is the first time I've tried using remote control. I seem to be experiencing this exact same issue but on completely different operating systems. CC is running on Linux and remote control device is an Android phone. I also tried using Brave browser as the remote on the same Linux machine.

Yeah I think it's a new backend behavioral bug on Anthropics side

Alright so idk if its fixed now or my workaround but it lasts basically the entire day successfully: open the same remote conversation in a browser tab on the computer its actually running on. This way it seems to never disconnect, I guess on phones and apps it's much more fragile. While on the computer the internet is always up.

Experiencing the same issue with a slightly different trigger:

1. Start a remote-control session and connect via mobile app — works fine
2. After ~10 minutes, switch to browser from a different device
3. Session crashes / stops working
4. Computer shows 0/32 sessions

The cross-device switch seems to reliably break the connection. No error recovery — have to restart remote-control entirely.

I have encountered the same problem.

It‘s the same situation.

Remote control didn't work for me even once. I tried from multiple networks (home wifi, work wifi, mobile), and I always get "An unknown network error has occurred. Please try again“

The session is visible and works correctly through web interface, which tells me it's specifically an issue with the iOS app.

Just updated to the latest Claude app on my iPhone, and it's still the same.
