As has been mentioned the return value from SSL_get_error wont produce any
meaningful results when passed to strerror.

The return value of SSL_get_error (as stated in the manual page) should be
interpreted as one of the SSL_ERROR_* codes. In this case '5' corresponds to
SSL_ERROR_SYSCALL which means the underlying transport returned an error code
when OpenSSL tried to use it which doesn't correspond to an I/O operation that
should be retried.

As mentioned in that manual page examining the error queue and/or errno should
give you more details.
