OneDrive for Business - "We can't connect to the specified sharepoint site"

I am unable to set up the sync on my PC for OneDrive for Business.

I go to my site online and click the 'Sync' button but I always get an error dialog box saying "We can't connect to the specified sharepoint site".

I am able to set up the sync on my laptop successfully. I was able to set up sync on my PC earlier this year before it somehow broke.

I have gone through the troubleshooting steps of running Repair, clearing Windows credentials, deleting the spw folder.

I have Office 2013 ProPlus on Windows 10.
