After applying ColdFusion patch update 13 my client is saying that he is facing issues with REST API services. REST API function that exists on production servers is not reachable by other servers. It was like few servers was able to reach and few were failing. What might be the cause for the issue and how to solve it.
These production servers make server to server calls, few were able to call and few were failing
Is it really because of patch update 13 in ColdFusion 11.
I think you'll really need to provide more information for anyone to answer your question. And while you're gathering that information, you might find the answer yourself.
Are you able to reach the APIs from the server console?
Do you have any errors in your CF server log? How about your web server log?
What kind of response, if any, are these other servers getting? 500 errors? 404 errors? Connection failures?
