This is because of the browser certificate.
You do not have to worry about this if you are using Chrome or Firefox internet browsers as it should allow you to continue to the site.
The Huawei router site might allow you to download the certificate for the site.
A message might appear that says 'Get Certificate" Or "Continue to the site", it might say not secured would you like to continue to the site?
Just click CONTINUE , this will stop you from getting the same message.
