Internal app sharing show downloading error | Error retrieving information from server. DF-DFERH-01

Question

I published my app in internal app sharing. After I shared link to download to myself, but to another account. I turn on internal app sharing in Google Play on my phone. When I click downloading, I catch error -> Error retrieving information from server. DF-DFERH-01

I tried to test in two phones, but with same google account.

Answer 1

There is a step I missed - testers have to opt in to the test program before they can use the shared link, and until they do they get the opaque DF-DFERH-01 error. On the Play Console under Release Management, select App releases. In Internal test track, click Manage. Under Manage Testers click the drop arrow. This opens up a panel, and near the bottom is an opt-in URL. Copy this and send it to testers. They have to click on this link and agree to opt in to the test program. They can then download the current version. After this they can also use internal app sharing links for new builds.

Answer 2

In my case, I was trying to access the internally shared debug app not a production testing app. For this, I was using Internal App Sharing feature. To be able to install and use such apps one's email needs to be added to an email-list(as per the settings we had) otherwise, anyone with the link can install.

Problem

The problem is despite having my email in the list, and email representing a google account I was not able to install it. I faced this error. Click here to see the Screenshot

Cause

I maintain about 8 google accounts on my mobile and I was logged in to all of them. I realized having multiple accounts is causing the issue.

Solution

Instead of logging out from all the google accounts, I simply created a new user in my mobile and set it up. Then I opted-in to Internal App Sharing in the App store. Then shared the app link via google-keep. Voila, I was able to install it.

Answer 3

In my case I just had to wait ~48 hours and it Just Worked with no other changes.

Answer 4

A few more silly things to consider if you are new to Google Play Console.

1. You need to make sure to enable Internal App Sharing on Google Play Settings, here is a tutorial for that.
2. Do not forget to publish your modifications by clicking on publication overview (sorry for the Portuguese language on the pic, but you can find through the icon):

And then publishing it by clicking on the blue button (publish modifications or something like that):

3. After doing this, try to clean the cache of your play store and remove all updates from play store (after doing this you'll need to enable Internal App Sharing again).
