Hello, all!

Have encountered the similar/same trouble.

OpenVPN 1.1.14 build 56 core 3.0 android armv7a thumb2 32-bit on Android 4.1.1.
When starting connection fails with "error rendering cert" in log, please see the screenshot (havn't found where the logfile is located).

Imported OVPN-file (key is revoked) is listed bellow.
It works fine with OpenVPN for Windows.

jatinkumar

for the Android software version : it is as below
OpenVPN Connect 1.1.14 (Build 56)
Open VPN Core 3.0 android armv7a
thumb2 32-bit

i also want to highlight few things...i have tested this profile on my laptop it is working fine so guess there is no issue with profile.
then i used mobile data network on my android and it worked charm .. every time..
1.tested on office internet with full access rights... NO success
2. tested home with my open braodband.. still nothing... 🙁
3. tested same at my client's place with their internet . still no go ;(
4. today i tested with other internet provider at my frnds place on android and it got connected...

from 1 to 3 above is tested on counties biggest and 85% user holding ISP. point four is the ISP who taks connected from point 1 ISP and doesnt even hold 1% of the internet here.. so not able to relate why traffic is not going through.

Any thoughts.

I found a workaround that worked for me, I discussed in this thread:
