TeXnicCenter + MiKTeX: "get host by name failed in tcp_connect()" when trying to install missing packages

I am using TeXnic Center with MiKTeX (both of these are the most recent versions, I literally just reinstalled while trying to fix this issue) on Windows 10.

I am trying to compile a .tex file from TeXnic center and it informs me that I am missing the bbm package: Image

I click install, but get the following error in the TeXnicCenter output log: Image

So I try again and this time I select to "Change" next to "<random package repository>". I select "Packages shall be installed from the Internet" and click "Next". That's when I get the following error: Image

Here's the error log I get when I click "Copy Info":

I tried to install the package manually with the MiKTeX package editor and it shows up: Image

Now I have a hunch that TeXnicCenter is looking for these packages in the wrong place, but I have now idea how to fix this.
