Hi, this error means that OpenPlanet stopped sending data to tmrl for some reason.

In which situation does this happen exactly?

[ger3tto]

when doing the test with screenshot enviroment

[yannbouteiller]

Can you have a look at the logs of OpenPlanet when this happens ?

Also, is the race on when you launch the script?
