I’m trying to use httpClient for the first time - but am getting an ‘unable to post’ error. And I think it’s related to an out of date TLS protocol. I am trying bypass_cert_validation, but am still getting the error. It works in postman.
Thank pturmel. I am encouraging them to upgrade their server; and I did also re-enable the old TLS by editing the java.security file and removing the references to TLSv1 and TLSv1.1. Then I restarted the server. That didn’t work for me.
It might be worth trying system.net.httpPost after having re-enabled TLS 1.0 in the Java security file. It’s a different implementation than system.net.httpClient and might allow TLS 1.0 if it’s enabled in general.
