I have an integration on oracle integration cloud which was running successfully, but suddenly it stopped with this error message appearing in trace
FailedAuthentication Fault Reason : FailedAuthentication : The security token cannot be authenticated
Any help will be appreciated
Clarification: This message refer to failed authentication that’s because of the credentials for one or more connections being used by your integration.
Resolution: get the list of connections being used by your integration then go to them and make sure of the username and password that they are correct by doing validate and test.
