Using Elektron SDK Java we can download and update the certificates manually using function
openssl s_client -connect chp02-emea1.thomsonreuters.com:443
openssl s_client -connect chp02-emea2.thomsonreuters.com:443
We would need to understand how we can automate this or why your client library doesn’t validate the certificate automatically.
What is the best practice? Or does your library have an option to disable certificate validation completely?
