HTTP Error:

ChrisBrook — Tue, 01 Dec 2020 11:11:00 GMT

Hi,

I'm trying to call a SOAP API using the HTTP Utility. I keep getting hit with the below error which is frustrating me!

"Exception: The underlying connection was closed: Could not establish trust relationship for the SSL/TLS secure channel.
Inner Exception: The remote certificate is invalid according to the validation procedure."

The annoying aspect is that if I use SOAP UI I can call the API absolutely fine!

Blue Prism Steps:

Load the certificate (Utility - HTTP -> Load Certificate)
Generate the SOAP Body (dynamic based on the case being worked)
Call the API as per the below setup

Any ideas would be much appreciated!

Chris

You can disable certificate validation and look at what you are actually getting in response.
Often it is your corporate proxy telling you that you need to authenticate, so check if you need proxy settings too.

Hi @AndreyKudinov

Thanks for your reply.
Couple of questions on that:

How?
How would that work when the API service requires 2 way authentication via a certificate?

1) https://digitalexchange.blueprism.com/dx/entry/3439/solution/disable-certificate-vbo
2) Service authentication has nothing to do with SSL error.
