Try
chmod 777 ~/mnt/mtp
then mount your file

Getting the same error. chmod didn't help.

For me this was caused by the phone not being set to "File transfer" in Android. To get this to work correctly I had to do:

1. Connect phone
2. Unlock the screen, set USB preferences to "File transfer"
3. Mount jmtpfs
