Check your Internet connection

Check your network cables, modem and routers.

Allow Microsoft Edge to access the network in your firewall or antivirus settings.

If it's already listed as a program allowed to access the network, try removing it from the list, and adding it again.

If you use a proxy server:

Check your proxy settings. You might need to ask your organization if the proxy server is working. If you don't think you should be using a proxy server, go to Settings > System > Open your computer's proxy settings.
