Good afternoon. After you install the root certificate on the server (Linux 3.2.0-4-amd64 #1 SMP Debian 3.2.73-2+deb7u2 x86_64) checking
openssl s_client -connect securepayments.sberbank.ru:443 -CAfile /etc/ssl/certs/ca-certificates.crt
It turns out the error:
Verify return code: 20 (unable to get local issuer certificate)
While than on the other server everything is OK. what could be the problem?
