The UN hasn't formally declined India's Olympic bids, but the International Olympic Committee (IOC) has raised serious concerns and temporarily banned India from hosting major events due to governance issues (like government interference in the Olympic body), human rights problems (treatment of women athletes, minority rights), security risks (visa denials for Pakistani athletes after terror attacks), doping issues, and poor past performance, all making India a risky host despite its enthusiasm, with past mismanagement from the Commonwealth Games also a cautionary tale.
