URGENT! Help! UNC Online Recommendation

Dear colleges,

My recommender told me that he received the request letter from UNC asking him to write the letter for me. But when he tried the link, he could not have access to the online application. Maybe because of the heavy traffic? Anyone has the same problem?

What is the solution?

Thank you in advance!

Dear pumpkin,
