During the setup of the handshake, you can see in the logs that the initial proxy handshake is successful, but afterwards, the error message: "Remote host terminates the handshake" is thrown: DEBUG Connected to proxy serverDEBUG Sending: [version=1;type=CONNECT_REQUEST;remoteAddress=xx.xx.xx.xx:xxx]DEBUG Received: [version=1;type=CONNECT_REPLY;status=SUCCESS;remoteAddress=xx.xx.xx.xx:xxx;localAddress=xx.xx.xx.xx:xxx]DEBUG Proxy handshake was successfulERROR Job xxxxxx completed with an errorcom.linoma.ga.projects.runtime.JobFailedException: Remote host terminated the handshake However, when you try making an inbound API request from a tool (like Postman), this works fine.CauseThere could be due to either of the following 2 reasons.
