javax.net.ssl.SSLHandshakeException: Received fatal alert: unknown_ca

Hey matijap,

There is a stackoverflow post that states i

"If you get an alert unknown_ca back from the server, then the server did not like the certificate you've send as the client certificate, because it is not signed by a CA which is trusted by the server for client certificates."

Also, just in case the above info doesnt help (although i expect it to), whenever i have an issue in soapui/readyapi that works fine in postman/insomnia, i always do a comparison of the requests RAW details from Postman/insomnia relative to the request details in soapui/readyapi as more often than not, the difference in the requests headers indicate the cause in some way.

So, try this.

1. Run request in Postman and grab the RAW request details and save them for later.
2. Run the same request in soapui/readyapi and grab the RAW request details and save them.
3. Publish the RAW details here (of both requests) people can then help with the comparison to help resolve the problem.

Cheers,

Rich
