Error on tracer opening



Systematic error on tracer opening happens in all browsers.

Error Messages

Tracer - PegaRULES - makeHTTPConnection(): Exception!!!

Steps to Reproduce

Log-In to Pega7 Developer Portal and open the tracer

Root Cause

A defect or configuration issue in the operating environment. 

 HTTP traffic logs must be examined to understand more.

  • Is there a load balancer / webserver between browser and pega for users who have the problem?
  • Is there a JS error? does the HTTP request go out of tracer window?
  • Please provide a fiddler/IE trace


Perform the following local-change: 

Using [email protected] tracer works normally. So I changed my AccessGroup setting the same [email protected] accesGroup (PRPC:Administrator). With this AccesGroup tracer work fine also with my Account. Then I restore my original AccessGroup and tracer is still working normally.
Probably It may have been a problem of dirty cache.
