I have known working schematics that times out with an ERROR while processing a simulation. If I keep trying, it eventually works. I'm guessing the easyeda server is too busy and the local processor times out. This has always occurred to some degree in the past but its really bad now. This is really a pain as it takes a minute or so to time out, and you don't know if you have an error in you schematic or the server is too busy. Its getting to the point that I can do the simulation calculations faster by hand. Can you increase your server resources or come up with a way to let us know its busy?
