After some time researching the cause of the error, I found out that it was due the DNS settings on my MacBook for the Wifi network I was using. If you are having the same issue, here is how I solved it:
- Open System Preferences…
- Click on Network
- With WiFi selected in the service column, click on the Advanced… button.
- In the Advanced… window, click on the DNS tab. It should look like below
- Under the DNS Servers column, click on the + icon to add a new DNS server address. Add the 22.214.171.124
- Add also the 126.96.36.199. address.
- Reorder the addresses as by dragging and dropping them as below:
- Click on the OK button
- To finalise, click on the Apply button.
That’s it! Refresh the web page you are trying to access in your browser and it should not work.
