Hi, @fixit7 .
I've never ran speedtest-cli but, after a web search, I've found the following Reddit post (in the subreddit "r/Linux4noobs") that was posted 23 days ago:
https://www.reddit.com/r/linux4noobs/comments/w6d5hg/speedtestcli_only_works_with_secure/
In that Reddit post, the original poster ("u/CryPTuuNe") wrote the following:
"(...) I just setup Ubuntu on my new PC. For testing purposes I installed the speedtest-cli and with the command Speedtest everything worked fine. I don't know what I did then, but now I am getting an http error 403 forbidden. But when doing speedtest --secure everything works fine again. (...)"
According to the "speedtest-cli" manpage - Ubuntu Manpage: speedtest-cli - Command line interface for testing internet bandwidth using speedtest.net - the "--secure" switch has the following meaning:
--secure
Use HTTPS instead of HTTP when communicating with speedtest.net operated servers
I hope this helps.
