ConnectionPoolTimeoutException error occurs when installing ServicePack in AEM 6.3 + AWS S3 environment.


Not applicable

I am trying to install SP1 on AEM 6.3. However, the following error occurs during installation and installation can not be completed.

After that I attempted to access AEM's login URL, but no HTTP response and no connection at all.

In the standalone configuration, I can successfully install SP1,

Using AWS S3 for DataStore seems to cause this error.

Please tell me the solution to this problem.

Thanks for the help!

AEM version: 6.3.0
