Hello,

 

We are making a Rest API to an endpoint that uses stunnel for their proxy.  We recently upgraded our integration engine and it’s running Java AdoptOpenJDK 11.0.15.  Since we’ve upgraded we can only successfully make one or two POST API calls then we get an error:

 

Caused by: java.io.IOException: Error writing to server

 

I did some research and found this version of Java has disabled named curves, part of it’s Elliptic-curve cryptography.  Is there any known issues with stunnel and the version of Java that’s being used or the disabled named curves?

 

Thank you,

Randy Curry
