Hi,
your example inbound path looks like you're still using B1iSN8.8: Be aware that B1iSN8.8 is out-of-maintenance since more than a year.
Please migrate towards B1iSN9.0, where an explicit certificate handling for https communication is supported.
Embedded B1i help/documentation should also give you the answers to your http inbound related questions.
Best regards
Bastian
