Openvpn disconnects with "Encryption failed" error (UDP) or loops through activating/activated/failed (TCP) (all versions)

[vanshyp]

The paid MacOS app fails to connect to SmartDNSProxy VPN servers. Using recommended Config Files for versions 2.6 and above for the VPN network of SmartDNSProxy. Also see this instructions page.

Two example ovpn config files for your convenience:
Denmark-Copenhagen_TCP443_SMART.txt
Denmark-Copenhagen_UDP1194_SMART.txt

Please advise on what to do to fix this. Thank you!

Hey, I'm travelling. I'll look into this tonight or early tomorrow.

@vanshyp There's a bug in the parser in that it cannot deal with data-ciphers. I'll fix it in the next patch, but in the meantime, you can work around the issue by replacing data-ciphers with cipher in the .ovpn files.

Thank you very much!

[vanshyp]

This does indeed fix the problem. Looking forward to the patch. Thanks for the quick reply!

Fixed in partout-io/partout#351

Will be in Passepartout 3.8.2
