The share file option uses the Pod internal IP to share, which is inaccessible outside of the cluster

[Barteus]

Go to the “Object Browser” tab, select the bucket and the file you want to create a link for, click on it to see its details. Select a share button on the top right and copy the share link from the popup window.

Expected
Use the IP/URL which will be accessible outside the cluster.

Workaround
Exchange the first part of URL with the "localhost" if port-forward or your external IP where it was exposed.
