First ensure you aren't trying to send a listing that is off market. Our system will not allow you to send off market listings to prospects. If your listings are still available but you are still getting this error message, please try logging out of your Nestio account and logging back in and attempting to send listings again. Sometimes if the page has been inactive for a while it will expire.
If these tips don’t work, please contact us using the Support button with a screenshot of your Nestio page when you receive the error and our team will look into solutions!
