Unable to open login prompt

I went to re-install the Minecraft Launcher using the AUR package minecraft.net directed me to.

It installed successfully and everything looked ok, except when I go to login with Microsoft it gives me 'ERR_NAME_NOT_RESOLVED (-105)' every time. Pressing the button to go back to the launcher just doesn't work and it tells me to restart. I did and nothing, I even rebooted the computer twice and still nothing.

 

I've posted one of these before, but testers were unable to replicate the error. I've included more detail here so hopefully you can find out what's going on.
