If you are getting this message when running a new Report, and all the configuration settings are correct then the issue is due to incorrect initialization of psreports or SchedulerTransfer servlet. This issue was resolved in 8.48.16 but appeared again in 8.50.10. To fix this simply do the following.
From the IE browser, just paste the following URL.
If using NON SSL
http://xyz.com:port/psreports/ps/
if using SSL
https://xyz.com:port/psreports/ps/
Replace xyz.com with the actual Report repository web server name and port with actual port number used. Also if you use non default site, then replace ps with the actual pia site name.
See the Metalink resolution :
E-RD: Reports do not post initially when the Web Server is bounced [Video] [ID 660253.1]
Other Option is to open a previously successful report that invokes the psreports servlet.
