Error while configuring LoadGenerator over firewall with SSL and client and server side certificates

While configuring LoadGenerator over firewall with SSL and client and server side certificates, below error occurs:

Error: Communication error: Failed to bind socket. A process on the machine is already bound to the same address. [MsgId: MERR-10344]

Error: Two Way Communication Error: Function two_way_comm_create_acceptor failed. [MsgId: MERR-60999]

Error: Communication error: SSL connect error : verify host failed : DNS fail with test [MsgId: MERR-10343]

Error: Two Way Communication Error: Function two_way_comm_resolve_userdata failed. Reason: invalid handle.[MsgId: MERR-60985]

Cause

According to R&D, QA testers have ran some checks & claimed that some configurations e.g. setting Use Server Certificates to High will not work. Explanation given was this was a planned feature that was never implemented, & also it hasn’t been tested by QA in recent versions of LR.

Similarly the use of client certificates might never have been implemented either.

Fix

As a workaround/alternative, R&D recommende to upgrade to LR9.5 to make use of the new feature (secure channel communication) instead of using SSL client and server certificates.

With regards to the new feature in LR9.5, the security implementation uses AES-256 (Advanced Encryption Standard with 256 bit key), and is a symmetric key encryption method.
