Well, I hardly ever use PPTP with my VPN provider as I either use proxy DNS or

F26 - Fails   (Same log entries that you've shown)
F24 - Works
Android 7 - Fails
Android 6.0.1 - Works

And so I followed up on your comments and tried F24 Live and it worked out of the box. Since it worked for me under F25 as well (not the Live install disk though) I can only think of a library that I must have installed at one point when using F25 which made it work.

Should I file a bug under bugzilla or wait until you get a feedback yourself?

Thank you.

Ok I found a solution right here: https://ask.fedoraproject.org/en/question/94500/connection-via-vpn-pptp-does-not-work-unless-firewall-is-disabled/

Basically GRE traffic is no longer allowed through the firewall so one need to do the following (as root):
firewall-cmd --permanent --direct --add-rule ipv4 filter INPUT 0 -p gre -j ACCEPT
firewall-cmd --permanent --direct --add-rule ipv6 filter INPUT 0 -p gre -j ACCEPT
firewall-cmd --reload
modprobe nf_conntrack_pptp nf_conntrack_proto_gre

And then it works for me.

Thank you.
