Linux, Android, .p12

Hi,
I am having a problem generating a .p12 file for RealVNC Viever correctly.

Android accepts the file, while the program responds that it cannot use this certificate for authentication.

Can anyone tell me how to generate using openssl on linux these certificates so that the program will recognize them? 

I tried with RSA and ECDSA with a P-256 curve.
When exporting I used "openssl pkcs12 -export -legacy ..."

If anyone has a ready script to generate for the server and client and would post it here, I would appreciate it. 

Sincerely
