Step 0: Are you in the right place?

For issues or feature requests related to the code in this repository file a Github issue.
- If this is a feature request please use the Feature Request template.
For general technical questions, post a question on StackOverflow with the firebase tag.
For general (non-iOS) Firebase discussion, use the firebase-talk google group.
For backend issues, console issues, and other non-SDK help that does not fall under one of the above categories, reach out to Firebase Support.
Once you've read this section and determined that your issue is appropriate for this repository, please delete this section.

[REQUIRED] Step 1: Describe your environment

Xcode version: 12.0.1
Firebase SDK version: 6.34.0
Installation method: **CocoaPods** | Carthage | Zip file | Swift Package Manager (select one)
Firebase Component: Storage (Auth, Core, Database, Firestore, Messaging, Storage, etc)

[REQUIRED] Step 2: Describe the problem

Firebase Storage uploading and downloading was working before. And now it is throwing An unknown error occurred, please check the server response." UserInfo={_kCFStreamErrorDomainKey=12, _kCFStreamErrorCodeKey=8, NSErrorFailingURLStringKey=https://firebasestorage.googleapis.com/v0/b/<project>.appspot.com/o/images%2Ftest.jpg?uploadType=resumable&name=images%2Ftest.jpg, NSUnderlyingError=0x6000033ca0d0 {Error Domain=kCFErrorDomainCFNetwork Code=-1003 "(null)" UserInfo={_kCFStreamErrorCodeKey=8, _kCFStreamErrorDomainKey=12}}, NSErrorFailingURLKey=https://firebasestorage.googleapis.com/v0/b/<project>.appspot.com/o/images%2Ftest.jpg?uploadType=resumable&name=images%2Ftest.jpg, _NSURLErrorRelatedURLSessionTaskErrorKey=( "LocalDataTask <4C208B43-2F70-42E4-9F36-3E5EF75D85CD>.<1>"

Steps to reproduce:

What happened? How can we make the problem occur? This could be a description, log/console output, etc.

If you have a downloadable sample project that reproduces the bug you're reporting, you will likely receive a faster response on your issue.

Relevant Code:

let storageReference = Storage.storage().reference(forURL: "gs://<project>.appspot.com/images/profileImg/" + Auth.auth().currentUser!.uid + ".jpg")
            let imageData = image.jpegData(compressionQuality: 0.1)
storageReference.putData()

// TODO(you): code here to reproduce the problem

@lawgimenez Thanks for reporting this. Are you seeing this from a specific (Mobile) network?

lawgimenez commented 3 years ago

I'm seeing this mostly on Emulators for now. I have not yet tested on real device. Will get back to you on that.

schmidt-sebastian commented 3 years ago

How are you connected to the Internet and from what region are you connection from? Are you able to use other Firebase services?

Please do let us know if this happens to occur on devices.

Just received info that this was because of the ISP I was connected to based on the Firebase Support email. I am connected on the ISP Globe Telecom from Philippines and it seems they are blocking Firebase Storage endpoints. I don't even know why or what is the reason for the ISP blocking it.

Thanks for following up. It would be best if you filed a Customer Support ticket if this issue is not resolved soon.
