Appstore Connect / developer.apple.com don't load

Trying to connect via Safari (Version 14.1.1 (16611.2.5)) to appstoreconnect.apple.com/login, it sits there with a spinner. I can see in the developer console:

[Error] Failed to load resource: the server responded with a status of 404 (Not Found) (app.css, line 0)
[Error] Failed to load resource: the server responded with a status of 404 (Not Found) (common-header.js, line 0)
[Error] Failed to load resource: the server responded with a status of 404 (Not Found) (app.js, line 0)

and those 404'd files:

https://appleid.cdn-apple.com/appleauth/static/cssj/1838721336/widget/auth/app.css
https://appleid.cdn-apple.com/appleauth/static/jsj/1725515964/common-header.js
https://appleid.cdn-apple.com/appleauth/static/jsj/623521622/widget/auth/app.js

I thought it was pulling bad files out of a cache, but wget says (for example):

wget "https://appleid.cdn-apple.com/appleauth/static/jsj/623521622/widget/auth/app.js"

So it looks like it's trying to pull in versions that don't exist.

I've cleared the cache, rebooted, etc. etc. The same happens accessing developer.apple.com It also happens in Safari Technology Preview. It also happens in Opera and Firefox.

It works in Chrome though. I'm using Chrome now to type this in. It actually might be in my version of Chrome's cache ( which I'm not going to clear).

Suffice it to say, this is mysterious and counterproductive.

  • I have the same problem with Safari, but it works okay with Firefox.

I am also experiencing the same issue. I was advised by an Apple support specialist to navigate to appleid.apple.com, login there (which is working for me), then while staying logged in, open a different tab and go to appstoreconnect.apple.com. This worked for me, and I am using this workaround for now.

  • Nice to know I'm not going nuts! Or: have some weird firewall blocking issue, although the fact that Chrome makes it through would count that out!

  • The appleid trick is not working for me; I just get the same waiting icon.

  • I don't think this is local, I've tried VPNs, different devices, different WiFis (and 5G) and all the usual restarts/clearing of cache etc and still no dice (directly at appstoreconnect that is, the appleid workaround is the only thing that works for me). @jhhl, are you able to log into appleid.apple.com? If so, try going to developer.apple.com > Account and then going to AppStoreConnect from there.
