CSRF Error while approving device through forwarded port

I am trying to approve incoming Device ID from a headless node using SSH port forwarding as described here:


I got remote syncthing running on http://localhost:9090/ as expected, and got a proposal to add device, but when I hit Add, an error box appears:

Connection Error
Syncthing seems to be experiencing a problem processing your request. Please refresh the page or restart Syncthing if the problem persists.

Chrome dev console shows CSRF Error in response.

The problem is caused by using two browsers on localhost interchangeably. Should synthing really care about CRLF in this case?

Yes, unfortunately.
