Error Connecting

Hello,

I am new to using tectonic and am trying to get it set up to work with neovim and vimtex. I am able to start the compiling process, but it fails with the error:

note: connecting to https://relay.fullyjustified.net/default_bundle_v32.tar
error: error sending request for url (https://relay.fullyjustified.net/default_bundle_v32.tar): error    trying to connect: tcp connect error: Connection refused (os error 111)
caused by: error trying to connect: tcp connect error: Connection refused (os error 111)
caused by: tcp connect error: Connection refused (os error 111)
caused by: Connection refused (os error 111)

How should I go about fixing this?

Looks like you need to fix your internet connection.
