Component used: Paging 3.0.0
Version used: alpha02
Devices/Android versions reproduced on: Nokia 7.1/Android 10

Steps to reproduce:

Clone the paging codelab on branch step11_loading_state: https://github.com/googlecodelabs/android-paging/tree/step11_loading_state
Update to the paging version to alpha02
Compile & launch sample app
Make the data load that fetches the 2nd page of Github repos fail (e.g. throw an IOException, use airplane mode etc)
Scroll all the way down to the "Retry" button
Observe nothing appears to happen when tapping the retry button

Sample project illustrating the problem attached for convenience.

I've confirmed the retry call makes it all the way up to PageFetcherSnapshot and is collected from retryChannel. From there I got lost in the world of suspend functions and breakpoints without any useful context...

Further observations:

Could not reproduce this issue with version alpha01.
Retry works as expected when the initial data load fails (set FAIL to ON_INITIAL_LOAD in GithubPagingSource to confirm)

Client WireGuard and OpenVPN have the same behavior.

Marked as fixed.

Same issue with surfshark. Have tried all protocols says connected but out going data.

I am using Norton 360 VPN, I was also suffering from this issue (the Key icon indicates I am connected to VPN but I cannot connect to websites etc.). My solution was to disable "Block connections without VPN" and it started working again. Unfortunately re-enabling it will cause the issue to come back.
