If you see this error, then you have the "Don't apply to jobs where the preferred freelancer location doesn't match the selected freelancer's location" checkbox enabled in the auto-bidder tab.
​
This allows you to avoid applying to jobs where the preferred freelancer location doesn't match the selected freelancer's location. In this case, the location of your freelancer does not match the preferred freelancer location, and therefore, the bid will not be sent. If you want to send a bid for this job post, send it manually.
