Suddenly I cannot access any https connection. Firefox shows an error

Error code: ssl_error_rx_record_too_long

Even I cannot access Google (http). It shows blank page most of the time. I did not do anything at all. I Googled about ssl error but all indicated apache2 virtual-host fact. But I don't have apache installed in my system. I did not change any kind of config file. So why is it happening?

I am using a modem (with WiFi router facilities). Other computers in this network are working just fine. I am using 12.04 64bit. System date is okay (synchronize with time server).


Make sure that port 443 is open and enabled on your server. This is the standard port for https communications.

If this doesn't solve your problem its better to connect to Firefox support

I've seen there problems like this but only for specific website and the solution was to remove some Addons so its better to tell them your peoblem in details if my answer doesn't help you

  • It is not firefox's problem.Same problem for chrome and chromium-browser. I am not running any server and do not use any proxy. How do i check open port?

  • iptables -A INPUT -i eth0 -p tcp --sport 443 -m state --state ESTABLISHED -j ACCEPT This command will open this port

  • It's the port for the secure connection

  • @IZX --- By default, HTTP uses port 80 and HTTPS uses port 443

    Yes, 443 is the port ON THE SERVER; the OP here has a problem WITH THE CLIENT.
