Thank you for posting the steps. It can always be useful though it may be late for someone 
.
I’m using Talend 7.3. I tried the steps you mentioned above but it still doesn’t work for me. I tested the connection using mongosh on the server from where I’m connecting. The only missing step is the tSetKeystore, but I’m not sure how to generate the TrustStore file If it’s required in this case. Any idea?
