A small dialog should appear. Click Start In Troubleshoot(Safe) Mode (not Refresh). Is the problem still there?

Hi There,

When I try and open this website https://www.appserv.com/ess/ I can do so on my desktop in the office, but not on any other device outside the office. My Desktop is Windows based and my laptop and phone are both apple.

Is this enough info?

Thanks, Nick

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

jamesafuf123 said https://support.mozilla.org/en-US/questions/1264659#answer-1237475 my ISP was blocking sites like that

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 There can be two possibilities: one is that the server is outdated and doesn't support modern cipher suites, another might be that the server only supports a few cipher suites and Firefox doesn't support any of these.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

Thanks for the feedback, it still doesn’t explain why I would be able to open it in Firefox on my desktop in the office?
