You encounter an error when including links in a Cover Letter that does not meet Upwork's acceptance criteria.
​
The error is not related to GigRadar's link usage restrictions but rather stems from limitations within the Upwork platform. ❗️
​

An 'unsafe link' refers to a link leading to another platform through which the freelancer and client can communicate outside of Upwork, violating the Terms of Service (TOS). More details can be found here:
