runtime error - websocket problem

posted

did something special happen to GE on 04.29.13?

i had successfully run an algo on GE from 01.01.02 to 01.01.04 dozens of times. then, all of a sudden, i got a runtime error stating "Something went wrong. Sorry for the inconvenience. Try using the built-in debugger to analyze your code.".

i tried closing the algo, didn't fix it. i logged out, didn't fix it. i closed my browser, didn't fix it. i send a troubleshooting email, no response yet.

i right clicked in the code window and clicked "inspect". that displayed a new window called console where i saw this message "websocket connection to ... url ...failed. close received after close.".

did more research. found out that websockets have been a quantopian issue in the past. also found out that they are a client side browser issue. tried using internet explorer instead of chrome, no luck. installed firefox, no luck.

went back to chrome and started playing with the backtest dates. the algo actually runs now as long as the starting date is 04.30.13. if the start date is 04.29.13 or earlier, the error message returns.

does anyone know what is going on here?
