Authentication with Apple Developer Portal Failed - socket hang up error during EAS build

### Build/Submit details page URL

_No response_

### Summary

I have an active, paid Apple Developer account with developer access. When I try to log in through EAS CLI to generate or validate build credentials, I consistently get an authentication error with the following message:

Authentication with Apple Developer Portal failed!
socket hang up
Error: credentials command failed.
I provide my correct Apple ID, password, and 2FA code each time, but the connection times out or hangs up during authentication.

What I have tried:

Verified that Apple Developer account is active and can log in normally on [developer.apple.com](https://developer.apple.com/) manually.

Provided correct Apple ID and 2FA code as prompted by EAS CLI.

Ensured the latest EAS CLI version is installed.

Cleared local credentials with eas logout and re-logged in.

Verified Apple Developer service status as operational.

Attempted multiple build profiles and skipped manual credential entry.

Checked for any network issues on my side (no proxies/firewalls blocking).

Waited for potential Apple server outages or API issues.

Please advise if this is an ongoing Apple server issue or if there are known workarounds/fixes for this connection termination problem.

Thank you.
