Trying to install a new app gives me a "Host violates local access rules" error

Hi folks,

I have been trying to download and install various apps such as “Files download limit” app from the apps store, however each time I try I get an error message:

“An error occurred during the request. Unable to proceed.
Host violates local access rules”

Is there some other configuration option I need to adjust in NextCloud that I am not noticing that is required to allow downloading and enabling apps?

I appreciate any light someone can shine on this?

Hello community,
I just did a fresh install and facing the same issue.

Any hints to resolve this?

best regards,
