Nextcloud AppStore Timeout

Dear lovely community,

NextCloudPi version: v1.24.0
NextCloudPi image: NextCloudPi_03-28-20
OS: Raspian GNU / Linux 10
Nextcloud version:
Hardware: Raspberry Pi 3 Model B v 1.2
PHP version: 7.3.14

I am trying to install the “OnlyOffice Community Server” app. After I click “Download and Activate” it takes a while to get the following error message:

cURL error 28: Operation timed out after 120000 milliseconds with 144572988 out of 315849196 bytes received (see

I already set the TIMEOUT value to 3000 in the „Client.php“. The error message mentioned above already refers to this change. Before I got the same error message only a little bit earlier (after 3000 ms).

It doesn’t matter what value I enter in TIMOUT, after 120000 milliseconds its over.

Does anyone have a suggestion to fix this bug?

Thanks a lot.

Lovely greetings,
