Why can't I open my Yahoo mail? ? Yahoo said: Yahoo said: I'm sorry for the inconvenience we caused you. If you accidentally encounter temporary problems, you can do it a little.

Yahoo mail cannot be opened for the following reasons:

1. The browser component is damaged, which affects the normal Internet access.

Number 2.2. DNS settings are wrong, which makes it impossible to access Yahoo Mail Server normally.

3. The browser security settings have been modified, which makes it impossible to log in to Yahoo Mail normally with the browser.

4. The browser cookies information is lost, so you can't access Yahoo Mail normally.

First of all, we should eliminate virus interference, install the latest version of Kingsoft Internet Security for quick killing, and let the running virus Trojans and rogue software be cleared at one time.

Then check the control panel-> The network is connected to the Internet. Check the tcp/ip property in the local connection properties (you can choose ipv4 and ipv6 for vista or win7 systems), and then double-click the ipv4 property. Check whether the dns server is set to automatically obtain the IP address specified by network management. If it is not correct, please revert to automatic acquisition, or try to use the free DNS server provided by google with IP of 8.8.8.8, and then click OK.

Finally, use the garbage cleaning function provided by Kingsoft Internet Security or Kingsoft Guardian to clear the browser history. Note that Clear All is selected here. After cleaning up, you need to re-enter your password to log in to the websites you visited before.

If the above method still fails, you can try it in the control panel->; Double-click the network and Internet connection icon, click Advanced in the pop-up Internet properties, and then click Reset Internet Options.
