Some website are opening fine but some are not, showing Secure Connection Failed PR_END_OF_FILE_ERROR. Even Google, Youtube are also showing same error page. I have tried every probable solution from internet. Even I have tried to open browser in Linux system installed in my pc and found same issue. This problem is coming from few weeks, previously it was fully ok.

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

jamesafuf123 said 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 There can be two possibilities: one is that the server is outdated and doesn't support modern cipher suites, another might be that the server only supports a few cipher suites and Firefox doesn't support any of these.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.
