Why am I getting the error 'Portal is not available at your location' while trying to access a Freshservice page?

This error is generally thrown when the IP from which you are looking to access Freshservice is restricted, provided your team has set up IP whitelisting to allow access of Freshservice from particular IP addresses only.

The navigation path to do this is Admin --> Channels -->Email Settings and Mailboxes --> Freshservice IP addresses for email communication
