I’m trying to delete a device on Mac OS X using 0.11.7 and every time I try to delete a device I get
"Syncthing seems to be experiencing a problem processing your request.
Please refresh the page or restart Syncthing if the problem persists."
I restart, shutdown and restart but yet still am having trouble getting past this problem. Any thoughts?
The Syncthing GUI uses cookies to maintain a session. You can’t have more than one session open against the same website in the same browser, much like you can’t log in as two different users on this forum at the same time from the same browser, so that may cause this issue.
Using some sort of proxy/SSH tunneling which causes the cookies to be issued under an incorrect domain causing the browser to refuse them.
Having some privacy add-on enabled in the browser causing cookies to be refused.
Browser failing to provide the initially provided Basic Auth header to re-authenticate given syncthing was restarted and the session cookie is no longer valid (refreshing the page usually fixes this)
Having multiple sessions for the same site (as calmh already explained)
