aaPanel_Kern Yes, I can take a shortcut by pulling with the command, and I've tried that.
But that's not the point. I'm asking this to find out what's really going on and what's causing it.
And it turns out the problem was with the Docker Acceleration URL, which is pointed to the daocloud server by default. The solution was very simple: I just needed to change it to No Acceleration (which should be the default setting).
I hope this helps others who have the same problem.
