If you have an old page bookmarked, you may need to update the link if it is no longer redirecting properly.
Try going to ebay.com and signing in there. Or else try using the My eBay link in the community pages, since you are already signed in here. You can reach that by clicking on the blue gem picture placeholder icon in the upper right.
You can also try bookmarking one of your My eBay pages after you sign in; using that link later, if eBay needs you to sign in to access the page, you will be directed to sign in, and then you will be sent to your page.
