If you click on a Private Project link but are redirected to the organization's Open Public Portal instead of the opportunity itself, then the following is possible:

1. The opportunity may not have opened yet.
2. The link could have changed or been pasted incorrectly in the communication sent to you.

To resolve this issue, please try the following:

1. Try highlighting the link as opposed to just clicking on it, then copy and paste it into your browser.
2. Review the communication that contains the Private Link to ensure that you are not trying to access the opportunity prior to the open date. 
3. Reach out to the Buyer and ask them to resend the link to you.
