Describe the Bug

On Mobile, using Brave, when we access a web app that has https enabled, we try to connect but the SDK is undefined.

We see the following errors on the Brave mobile logs when the page first loads:

Raw logs:

[Warning] [blocked] The page at https://192.168.1.67:5173/ was not allowed to display insecure content from user-script://null/index.iife.min.js.map.

[Error] Not allowed to request resource

Expected Behavior

We should be able to connect the accounts on Brave @ iOS

To Reproduce

• Use Safari Web Inspector to view the Brave logs on your mobile device.
• Run the example app.
• Open Brave on your iPhone and access https://<your_local_network_ip>:5172/.
• Hit the "Connect" button.
• Nothing happens. SDK is undefined.

Hi @andremfaria ! I gave this a try but wasn't able to reproduce the issue although I'm using the latest version of the SDK. For sdk-react we're just about to release a new version, I'll update this issue once we do so that you can give it another quick go.
With this specific dapp I was able to get an issue related to the selectedAddress which is somewhat expected since brave has it's own provider injected. Will sync back with the team about this.

Hi @andremfaria ! I'm going to close this issue to avoid having stale issues open. Please feel free to give as a ping with a new issue or through a comment so that we can open a new issue.

Hello, @christopherferreira9 . I tried with the latest version (0.26.3), and the problem persists. Please note that in your video, you are testing in a test app using HTTP. This issue only occurs with HTTPS. You can check this reproducible code: https://github.com/andremfaria/mm-sdk-brave-ios-problem.

@andremfaria I'm reopening this issue to investigate further.
