I cannot figure this at all. Out of the blue, on Thursday I started seeing “I/O Exception: peer not authenticated” trying to post (or do anything) from our site. There was a similar case #1444, but that fix (which involved CF certs on the web server) did not explain the fact that the requests were failing on production, staging (different host), as well as my local dev. For troubleshooting, I created a new test app on the same account, ran an oAuth test - same result. I even created a new app from another account pointing to a different URL, updated the consumer data in my code and got the same error! I literally have no clue how to proceed at this point. Any insight or additional troubleshooting suggestions would be more than welcome.
