Hi @kishorekumarit can you check you have the latest firmware and if cannot update over the air should be able to download to USB and update that way. it seems you are based in Middle East/Asia from the model no. In the UK 1560 is available.
If that is not the issue I would firstly suggest a factory reset , otherwise switching off Tv for a minute and rebooting router. Another idea is to change the DNS settings. Go to Network-Network Settings-DNS Settings. Change from Automatic to to 220.127.116.11 or 18.104.22.168.
