I"m using SLM from NCS 1.6.1.
I'm testing HTTPCREQ with HTTPC port 443 and security tag = 1. After I reset SLM, my send is successful and passes server validation checks. If I repeat the procedure sending the exact same data, the server is detecting a validation failure indicating something in the data has changed. The only way to get a successful server validation is by reseting SLM. I suspect there is some state that is not complete reset by XHTTPCCON=0 in the TLS implementation. When I test the same with non-secure HTTP (port 80) to postman-echo my payloads are identical.
Is there any equivalent to postman-echo with an https variant?
Any idea why it breaks after the first successful attempt?
