Hello Dave,
OpenSSL: error:0B080074:x509 certificate routines:X509_check_private_key:key values mismatch Cannot load private key file /etc/openvpn/client.key Error: private key password verification failed
It seems to me that you have missed a step:
The private key needs to be extracted from the YOURCALL file.
This is in the file .tqsl/keys/MM0RFN and needs to be in /etc/openvpn/client.key
Be carefull to copy only the key and nothing else from this file. Also do not copy "<PRIVATE_KEY:916>" from the first line just the "-----BEGIN PRIVATE KEY--- --"
Unfortunately if you manage to setup correctly openvpn on your machine, still you are not going to have fun with AMPR, as the server certificate has expired. I have sent an e-mail on this list but it seems OH7LZB is not reachable from here.
I hope this helps
