I am not a geek, and the documentation about this problem elsewhere in Mozilla support is way over my head. I just need plain language - and maybe visual - instructions on how to stop getting this error message. It never happened until a Firefox browser update a few weeks ago (September 2021). Often if I click the 'try again' button a couple of times, I can finally get through to the website I am trying to connect to, but this shouldn't be happening. It's annoying. I use Avast antivirus software if that's useful info. thanks.

radi.stoyanov said Turns out the option DNS over HTTPS is what caused the problem.

cor-el said This usually means that Firefox wasn't able to find a cipher suites to use to connect to this server and reached the end of the list. There can be two possibilities: one is that the server is outdated and doesn't support modern cipher suites, another might be that the server only supports a few cipher suites and Firefox doesn't support any of these.

You can check your browser and possibly compare this with the server setup. https://www.ssllabs.com/ssltest/viewMyClient.html
