Openvpn not connecting on android 5

Post by Rutherb » Wed Nov 21, 2018 10:39 pm

Hi,
I have been using openvpn connect for about 1 year successfully on Windows 10, iPhone 5 (iOS 10.3) and Samsung s3 (android 4.3). I recently got a Samsung j3 2016 running android 5.1.1. I installed the openvpn connect app on the j3 and installed the same profile I use on the Samsung s3 but when I try to connect the vpn on the j3 it just times out with message "server poll timeout, trying next remote entry...."
It is trying to connect to the correct dns on port 1194 via udp.

Does anyone know why I connect ok on my s3 using android 4.3 but not connect on my j3 using android 5.1.1 when both are using the same profile?

Hi TinCanTech - I have set the logging to verb in the config files and re-ran the attempt to connect. When I try to connect using the J3 I get no logs in the /var/log/openvpn.log and the connection still times out. When I connect using the S3 the connection does work and I get the below logged in /var/log/openvpn.log - should I be looking at different logs to get info on the J3 issue?

Logs from successful connect with S3 (logs updated to remove ip addresses)

Resolved this thanks it was a simple mistake in transferring an incorrect version of the profile to the new phone :-(
