Can you try: Sometimes, if you can't get it done, try the tips below. -Use local auto router rather than cloud server. -Make sure PCB rule doesn't have 3 decimal places, EasyEDA only support 2 decimal places. -Skip the GND nets, add copper area to GND net. -Use small tracks and small clearance, but make sure the value is more than 6mil. -Route some key tracks manually before auto routing and ignore them when auto routing. -Add more layers, 4 layers or 6 layers. but that will make more cost. -Change the components layout, make them have more space between each other. -Don't make any via/pad overlap the different objects which can be set the net. -Stop the auto-router, close the script, and re-open the script to run local auto-router server again. -Sometimes, The auto-router won't work at the first time, please modify the layout and try serveral times.
