Something is blocking calibre either an antivirus or a firewall. Exclude calibre.exe and calibre_parallel.exe from these and you shoul dbe fine.

I even tried switching to another PC and I've tried using Calibre to download the metadata on Linux, but it still doesn't work. I was able to use other functions that required Internet access such as grabbing news, but only the downloading metadata isn't working.

THen the firewall is on the network path to the internet. Look at the errors they are all timeouts which happens when something is blocking.

I think that it could be a problem with the site where the metadata was downloaded, so I found another plugin that download metadata on github.
Link of the plugin: https://github.com/fugary/calibre-douban
In fact, I can download metadata using an Amazon plugin, but I need to switch the server to China and the Amazon plugin isn't supported to download 'isbn', so I give up it.
