Description

I’m experiencing an issue where, with a custom reachability URL configuration, calling NetInfo.refresh() causes isInternetReachable to temporarily report true even though the device is offline. This brief incorrect online status can lead to unintended side effects in applications that rely on accurate network status, such as triggering paused mutations or other network-dependent operations.

Reproducible Demo

I’ve created a minimal reproducible example demonstrating the issue, which is available at my GitHub repository:
https://github.com/yahya-evoly/NetInfoRefreshBugDemo

Details:

• With the reachability URL set to fail, isInternetReachable correctly reports false.
• Upon calling the “NetInfo.refresh()”method, isInternetReachable changes to true momentarily before reverting to false.

Request

Could you please investigate this behavior? Is this a known issue or a bug that can be addressed? Ideally, isInternetReachable would consistently report false when the reachability URL is set to fail, regardless of NetInfo.refresh() calls.

Any guidance or workaround would be greatly appreciated!
Thank you for your time and assistance!
