Does “onedrive err_ssl_protocol_error” look familiar?

What if your OneDrive doesn't work because “View Online” and “Share a OneDrive Link” takes you to a page which says:

This site can’t provide a secure connection uses an unsupported protocol.


and looks like this:

There's a number of potential causes – but here's what caused the problem for me, as a resident of England, using BT Internet as my ISP … the problem was BT Web Protect. Fortunately, it's very quick and easy to resolve this issue in 3 simple steps:

How to turn off BT Web Protect
  1. Login to BT here
  2. Scroll down to ‘Manage my extras'
  3. Select Turn Off in the ‘BT Web Protect' (find this on  ‘Your included extras' page )

What if this didn't solve your problem with “ uses an unsupported protocol” ?

Not to worry – I spent some time considering why BT Web Protect stops OneDrive from working, and I believe it's ultimately down to the DNS server. BT Web Protect is preventing us from connecting to OneDrive through the browser, so here's how you make View Online work, if disabling BT Web Protect doesn't solve the problem.
