Web and Desktop both use a network connection to run simulations.

Your project is private so only you can see it to advise further.

Simulations using the web version work OK for me as at 221208 1603 hrs GMT..

@andyfierman Im share progect and run simulation now, but get error in WEB 

Empirically, it turned out to start the simulation by forcibly specifying the tran. 0 1 0 10 However, the default is tran. 1 Hope this helps someone. google translator translated this text for me)))

EasyEDA uses LTspiceXVII as the simulation engine. Most of the time it is only necessary to specify a Transient simulation in the form of: .tran Tstop Where Tstop is the time that the simulation is required to run for. It is not normally necessary to specify the maximum timestep. You will find more information about setting up and starting simulations in the Simulation Tutorial, (3) in (2) in: [https://easyeda.com/forum/topic/How-to-ask-for-help-and-get-an-answer-71b17a40d15442349eaecbfae083e46a](https://easyeda.com/forum/topic/How-to-ask-for-help-and-get-an-answer-71b17a40d15442349eaecbfae083e46a)

It is a little strange: sometimes your simulation runs OK with **.tran 1** At other times it does not run and produces the ERROR: error message. When this error message is produced, **Simulation > Show Your Simulation Report** shows the simulation report from the simulation run before the one that generated the error so is of no help to diagnose the problem. Sometimes when a simulation fails to run properly, you can try changing the value of Tstop a little like this: **.tran 0.999** or **.tran 1.001** Sorry but this sort of behaviour can occur with most simulators and is not specifically a bug in EasyEDA.

@UserSupport, I am now seeing this issue even in very simple simulations. @raai.el55, Please change the Category of this topic to Bug Report.

@andyfierman Hi it seems works now
