Mods of the workshop were downloaded repeatedly after reinstalling the game, but none of them succeeded

After the Don’t Starve Together was updated, the game could not be started due to the network switching during playing the game. It keeps showing that it is being updated, and there is no response after waiting for several hours. Then I tried to restart the computer, but it still didn't work. In desperation, I uninstalled all the contents of Steam and Don’t Starve Together,  then reinstalled. After that I found I can play it without mods, but almost can’t use most of the modules. All modules have not been updated recently. After subscribing to the modules, these mods has been downloading them repeatedly. I have been waiting for three hours but only few of them can be downloaded successfully. It also fails when I enter a server with modules. Before the update, I had no problems using the modules of the steam workshop, and the download process was very smooth. I have spent two days trying to find the problem. I want to know which  should I turn to for help in this kind of situation, whether it is Steam or Klei Entertainment? I would be very grateful if you could give a solution. I was so frustrated that I couldn't play Don't Starve for two days, and I hope to solve it quickly.
