Hello,

Around Friday (5/22/2026) evening, I have noticed that I was suddenly unable to properly authenticate to the Yahoo Fantasy Sports API, which I have used for several months with no issues.

Issues I have seen:
Unable to access my apps page: https://developer.yahoo.com/apps/
I see the error message: `An internal error occurred (eid 7280011)."
Unable to access the create apps page: https://developer.yahoo.com/apps/create/
I see the error message: "upstream connect error or disconnect/reset before headers. reset reason: connection termination"
Unable to authenticate with Oauth, with no changes to my apps (since I am unable to access them)
Attempting to authenticate delivers me to the link: https://login.yahoo.com/oauth2/authorize?src=oauth&done=https%3A%2F%2Fwww.yahoo.com
Which displays "Not Found" on the page
I just wanted to provide notification for these issues and hopefully they can help with the quick resolution.

Thank you,

Jake
