error when trying to open shared file

[navid-shokri]

this error is shown when the receiver (Marie) tries to open OCM-group shared file:

This happens for shared files and folders. No matter if it is a remote user share or a remote group share.

In case of shared folders, the size column writes "pending" and in case of shared files, the preview doesn't appear and the file can not be downloaded and the size always says <1k.

I put logs on the point the provider receives the request for the file. Which is on lib/composer/sabre/dav/lib/DAV/Server.php:253 that calls invokeMethod function on the same class and finally on line 488 the response is sent which is a successful 200 response.

On the receiver side the error says "connection refused" by the provider. Here are the logs that the receiver produces:

The trace leads to core/lib/private/Files/Storage/DAV.php:361 in which a GET request is sent to the provider. I tried to put a log on it (directly through docker exec) but the logs don't show up as if I am putting the logs in the wrong place but I have double checked everything.

My goal is to make the same call that the receiver makes and see if the connection actually gets refused. If it doesn't, the problem must be on the receiver side otherwise on the provider side.

In any case I am thinking that this might be due to the apache setup in our dev environment somehow.

Unlike #189, this is fixed in dev-stock main branch, at least for folders, look:
