Hi, I just noticed, that images i get using getFilePreview form Appwrite 1.6.2 (self hosted) are not shown anymore. I get "Response was blocked by CORB (Cross-Origin Read Blocking)".

I also noticed, that in the response headers for the getFilePreviewRequest, Access-Control-Allow-Origin is set to https://localhost. All other request (Database, Account etc.) have the right url there and are working as they should.

Everything in the App seems to work.... Exept the Images...

Any Idea what i should check or do?

When i try to shutdown Appwrite I get the following error: failed to remove network appwrite: Error response from daemon: error while removing network: network appwrite has active endpoints (, , , , , , , , )

TL;DR
Issue with Appwrite 1.6.2 showing CORS error for getFilePreview, while Database and Account access works fine. Response blocked by CORB. Access-Control-Allow-Origin set to incorrect URL. App shutting down due to active endpoints in network. Solution: Check and correct Access-Control-Allow-Origin URL for getFilePreview request.
