I'm having the same issue. Used to work on Ubuntu 16.04, and then somehow failed. I have a Ubuntu 12.04 next to me a it connects to the same PPTP with success.
I have attached a syslog of both machines. Let me know if I can test anything else. Thanks. ** Attachment added: "Here is a syslog dump from a failed 16.04 attempt, and a successful 12.04 connection and disconnect." https://bugs.launchpad.net/ubuntu/+source/pptp-linux/+bug/259698/+attachment/4781520/+files/pptp_fail_ubuntu-16.04 -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/259698 Title: pptp vpn service stops unexpectedly To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/pptp-linux/+bug/259698/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
