Android Play Store - Error retrieving information from server. RPC:S-2:AEC-2

Question

While installing specific app, the error popup is shown with error: "appname" could not be downloaded due to error. (Error retrieving information from server. [RPC:S-2:AEC-2])

I have already tried

1) restarting device

2) clear data from google play services

2) remove google account and sync again

The thing is, every other app is being installed and updated smoothly. I believe that there is something wrong with that specific app (and not with google play. Let me know if i am wrong). Found the similar question on link with same error code but with no solution.

Answer 1

One of my customers had the same issue. I sent him this link https://support.google.com/googleplay/troubleshooter/4592924?hl=en&rd=1 and it solved the problem. So try to:

• Restart your phone (it helped in my case)
• Check your data connection
• Make sure Download Manager is turned on
• Check your device's available storage
• Clear cache & data
• Reinstall Play Store updates
• Check for system updates

Also, if old version has been installed(or app with same package name, etc.) - try to remove it. Let me know, if it helps.
