All I was saying is that using a browser, cloudflade doesn't block my IP

get the same 1020 error you did, so there are "other factors" that
cloudflare objects to, as well as IP addr.

One factor might be the UserAgent, so I was asking if you might have
installed a browser add-on to modify your UserAgent string?

Not knowingly. According to
https://www.whatismybrowser.com/detect/what-is-my-user-agent

My string is:

Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:87.0) Gecko/20100101
Firefox/87.0
