I ran the ipsec start --nofork command
As you mentioned in your earlier reply the issue is indeed with loading the private key . It throws the following error 

-------------------------------------------------------------

00[CFG] loading secrets from '/etc/ipsec.secrets'
00[LIB] L1 - version: ASN1 tag 0x02 expected, but is 0x30
00[LIB] building CRED_PRIVATE_KEY - RSA failed, tried 5 builders
-------------------------------------------------------------------

What could be the reason for this ?

Here is the complete verbose stdout I got .. Thanks in advance for your help.

Try to start charon in the foreground using
 ipsec start --nofork
