[Bug] Iphone can not use Paidrop, why?

[GOgo8Go]

Unable to Use Pairdrop on iPhone

Issue Description:
Pairdrop is not functioning properly on iPhone devices. Specific issues are as follows:

The page loads successfully, and the network connection is normal.
Random naming shows "Loading" and never completes.
Clicking the paperclip icon at the top for pairing results in no response, as if the network is not connected.

Steps to Reproduce:

Open https://pairdrop.net/ on an iPhone device.
Wait for the page to load the random name (stuck at "Loading").
Click the paperclip icon at the top to attempt pairing—no response.

Attempts to Resolve:

1.Using mobile data: did not work.
2.Using a VPN: did not work.
3.Switching browsers (Firefox, Brave): did not work.
4.Trying other iPhone devices: did not work.
5.Self-hosting the Pairdrop project via Docker: the issue persists.
6. On a Windows computer using Firefox, the same issue occurred initially, but enabling the WebRTC feature in the browser resolved the issue, allowing successful pairing.

Expected Result:
Random names should generate normally, and pairing should function on iPhone devices.

Actual Result:
Random names remain stuck at "Loading," and clicking the pairing button yields no response.

Additional Information:

Network Environment: Mobile data, Wi-Fi, and VPN have all been tested.
Browsers: Safari, Firefox, Brave all have the same issue.
Devices: Multiple iPhones exhibit the same problem.

Suspected Cause:
Possibly related to network request restrictions or WebRTC compatibility issues on iPhone devices.

Requested Solution:
Please provide a resolution or specify any required configurations (e.g., enabling WebRTC) to resolve this issue.

What iOS version are you using?

[GOgo8Go]

sorry, it's 15.1、13.3. what's maybe the reason?

[schlagmichdoch]

As of now PairDrop has only been tested on versions iOS 15.3 onwards. I guess some web technology that PairDrop uses is not supported in the Safari version that your iOS ships with which results in an unexpected error. It maybe catchable but not sure how great the impact would be.

What’s your reason not to update your iOS version?
