Error Message when running API GET Request

Hi,

I’m trying to perform a GET request using an RESTful object in Katalon. Up to a few weeks ago, it worked fine but it seems it broke in the meantime, as I can’t get a response. Instead, I get the following error message:

javax.net.ssl.SSLHandshakeException: java.security.cert.CertificateException: No X509TrustManager implementation available
at org.apache.http.conn.ssl.SSLConnectionSocketFactory.createLayeredSocket(SSLConnectionSocketFactory.java:394)

Strangely enough my friend can get a response from the API using Katalon on his system, so what’s happening here?

I don’t know what’s happening there but this search may help:
