[strongSwan] Strongswan on Ubuntu - Failure to connect from Windows 10 client -error: deleting half open IKE_SA with 154.**.***.** after timeout

[MOSES KARIUKI]

Hello Vasilyev,

I can't get this to work.  *openssl -noout -text -in ca-key.pem. *I have
tried Googling but this also gives nothing.
        openssl x509 -noout -text -in ca-key.pem

Any ideas. Sorry I am a newbie on this one.
