In the log file you sent, it seems you tried to share a z drive but you or something cancelled the authentication prompt and then apply all changes. It’s difficult to understand if where the problem came from the failed drive share or the localhost port mapping action.
To help separate the issue, it would be easier to have a single action in the log file.
One way of achieving this is to follow this :
Could you try, setting the localhost port mapping on again,check that Docker is running properly, Then close the app.
Restart it again then Check the localhost port mapping, and see if it runs properly and send the latest log file to us.
