KB-2080 All integration calls consistently return "Connection timed out"


When a user makes integration calls (e.g. to https://google.com), the system returns a "Connection timed out" error. However, when using the a!httpQuery("https://google.com") function in an expression rule, the connection is successful. 


This occurs because HTTP Proxy is enabled in the Admin Console, which is blocking the integration calls.


Go to the Admin Console and click on HTTP Proxy under the Integration section. Review the HTTP Proxy settings or disable if the HTTP Proxy is not being used.
