This refreshes your network equipment and makes temporary errors clear. Also, reset your connection by flushing your DNS and refreshing your IP by using Command Prompt (ipconfig /flushdns, then ipconfig /release, and then ipconfig /renew).
2. Network Adapter Settings Check
Make sure that you rent IPv4 address on your network adaptor. Open Network and so on, and a sharing centre, and then open the change adapter settings. Right-click on your connection, select Properties and make sure that the box with the name: Internet Protocol Version 4 (TCP/IPv4) is marked. Then click it and then hit Properties and ensure both IP address and DNS server are set to obtain automatically unless there is a need to set it to static.
