when I enter to server list and I do refresh I don`t see any server and my internet crash

I`ve DIR615 E4 so I don`t have any firmware update

Your Internet crashes, when you try to reach a server? Have you tried reinstalling? What device do you use to connect to the Internet?

no I am not see any server at all the server list is empty and yes I tried to reinstall still not working

what do you mean what device do I use?

Do you use a LAN-cable, a WLAN-stick etc...

lan cable.

Is your router up-to-date? Have you tried a VPN?

I think my router is up-to-date beacause I checked in D-link support and to DIR615 E4 there is no update only for E1 and E3.

What is VPN and how do I use it?

Someone???
