I don't know why this topic marked as solved. Clearly there is a problem with signing in auctions panel.
I've registered auctions with help of cs. But there is no way to sign in auction panel. Page redirects to https://www.godaddy.com/help/godaddy-auctions-1000016.
I tried incognito, removing all caches, new browser etc. No way. Its really a big issue but we cant get a proper solution.
There is likely an issue with your direct auctions account, please call customer support directly or email us at Auctions@godaddy.com with your customer number so we can research it further.
