Core Apps » Orbot

I've been running with orbot for a couple weeks on my Nexus 6P, last night I tried to start the same install of orbot I've been running again after rebooting. (Version 15.0.1-RC-3-PIE - 7/18/15 - 8.0MB, from F-Droid, see issue #5521 to see how I got to this version) It seemed to start normally, then I got a message in the system tray which had an icon of a stopsign with an exclamation mark and the message "unable to start tor".

I re-started the phone, opened orbot and got the same message again. I copied the text from the menu and had the following:

Unable to start Tor: net.freehaven.tor.control.TorControlError: Error reply: Authentication failed: Authentication cookie did not match expected value.
Set background service to FOREGROUND
TorService is shutting down
Using control port to shutdown Tor

I tried stopping and restarting the connection and then had the following:

Unable to start Tor: net.freehaven.tor.control.TorControlError: Error reply: Authentication failed: Authentication cookie did not match expected value.

Set background service to FOREGROUND

Not sure what all that means, but at the end I still have the failure message in my system tray and no tor connection.
