I tryed now around 10 other configs.... all with the same result.



I also add the Files: ca.crt client.crt client.key in the Addition Folder keys.

The Certificates are SHA1. See Attached Files.
       

I Upload the Config to the Phone and a see vpn.cfg that i can Enable VPN.

After i commit, the Phone restart and nothing happen. i say its "enable" but on the Display i cannot see a V other something like that.



If i Export the Logs... there is nothing... no error...

in the Boot Log there i only one Entry SYS<6+info> run openvpn nothing more...

i also setup a syslog Server... but there is also no realy message... what can i do?


Any Idears? I Reset the phone 4-5 times.... and on the OpenVPN Server there is NO Connection.....

Best Regards,
Marcel

ok, downgrade to Firmware v82 work.

@Yealink please fix this problem in V83 Firmwars, or give Input what we have to change!.

Try upgrading to V84 firmware it is out and commonly available now.

I have done testing and had no issues with OpenVPN holding a stable connection for 5+ days on a T41S running version 66.84.0.10.

Now I have not tried loading verison 83 firmware to confirm that it is definitely broken, but enough people have reported issues so I just assume the problem has been fixed in version 84. Try upgrading and post back your result so we can know for sure.
