I can't renew the token

My English isn’t good. Sorry!
Now I have a problem: I can’t renew the token. The page that keeps coming up when I try has a link, but it doesn’t work.
Is my Mac too old - 2012?
iOS 10.14.6
Thank you!

It seems that the eBay authorization page doesn’t work well under older versions of macOS but there is a work around available.

Seems to be hitting here in the USA as well. 9.9.2b3
I am using 12.7.6 os because I am using an intel based iMac. I guess my days are numbered to Dec 5 2026?
