Hi .
The UDN is a private support site, and while your company does have access, you have not specifically been setup for access yet. Please reach out to the group administrator within your company for access. If you don’t know who that is, you can send me a private message here on the forums.
I’m going to close this topic now, since the forums is not the correct place to get help with general account issues. For customer/account support, please visit Epic Games Technical Support & Customer Service | Epic Games
Thanks
