Https connection error of Flow with web Service

Hello. I have a web service which works fine calling it from browser, (returning some json), but it can not establish a connection with a flow HTTP action with the same url.

The application is registered on azure portal and has uploaded public key for a self-signed certificate for openssl.

Hi @kpavlidis ,

 

Per my certain research, I found that error message “Could not establish trust relationship for the SSL/TLS" could be caused by:

  • You’re using an invalid certificate
  • The certificate wasn’t issued by a trustworthy authority.

Please check the following doc for resolution:

Best regards,

So while it is working from browser without problems, flow does not accept this self-signed certificate? If this is the problem how do i create a self-signed certificate that will be acceptable?

 

Also where to install the cert since it is a flow?

Did you ever get anywhere with this? I have the same problem. 

Authentication is not the problem, its the self signed SSL certifcate on the target web service that "not trusted"
