Am I the only one experiencing Internal Server Error 500 “There is no valid session for the current request.” while trying to open my DSP? On a Dashboard I can read that “This DSP is alive and well. Click on the name above to launch.” but when I click it I get the 500 error. It is Free Hosted Edition . ---

No, this is a known outage of the free hosted sandbox environment at this time. Your production DSP environments, if any, are not affected. I will update this thread once I can confirm resolution. ---
