We have implemented SAP HCM 6.0 with SP 57 in one of our clients. We have gone live with OM, PA, Time, PY , Travel, Appraisal & ESS-MSS. Now we are in the process of launching ESS through internet. We are encountering a problem only with respect to ITS links e.g. Approve Clock in & Clock out correction and Training Appraisal. We are not able to access these links. However, we are getting following issue.
The proxy server received an invalid response from an upstream server.
The proxy server could not handle the request
Reason: Error reading from remote server
Apache/2.2.15 (Red Hat) Server at testsciabapportal.sci.co.in Port 8000
We are not able to resolve this issue.
