When opening the file manager within a game server instance, the error shown in the screenshot is displayed. So far I have not been able to find a cause. I have already deleted the browser cache and reloaded the page. Installed is the panel version v2.4.2, built 21/02/2023 11:49 on Debian 10.
Known bug, next update has a fix.
Is there a workaround to make this work?
