I'm trying to connect to a REST API which requires a certificate in order to authenticate the request. I have managed to get it to work using Postman, and I have installed the required certificate on the same server as AwareIM, but when I try to make a request in AwareIM I get the following error:

Is there something special you have to do in order for AwareIM to recognize or use the ceritficate when sending a request? I've tried this using verison 8.8 of AwareIM.
Has anyone encountered this or a similar problem when working with certificates in AwareIM? And if so how did you solve it?
Thanks in advance!
