The IXWebSocket code may simply not support IP address certificates.  It
may be treating a dotted-quad IP address string as a hostname, which it
then fails to match.

The OP reports:

    OpenSSL failed - error:0A000086:SSL routines::certificate verify failed

The OpenSSL error stack would typically have more detailed error
information if more than just the last error were reported.  If the OP
has additional error info, that'd be very useful.  If not, the
application should really have done a better job of reporting error
conditions.
