Recently, two sites have given me 'Secure Connection Failed' errors. One was 'SEC_ERROR_BAD_SIGNATURE', the other 'PE_END_OF_FILE'. These sites have worked fine for years, now they don't.

Microsoft Edge has no trouble with either site.

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 There can be two possibilities: one is that the server is outdated and doesn't support modern cipher suites, another might be that the server only supports a few cipher suites and Firefox doesn't support any of these.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

Do these websites support a secure HTTPS connection ?

Can you post a link to a publicly accessible page (i.e. no authentication or signing on required)?
