After translating your question, this is what I understood: we can't connect to the Azure file storage (Z drive) when changing the Wi-Fi network while working from home, but it works when sharing data from a mobile phone's internet connection? We would like to ensure consistent access to the file storage, even when not connected to our office's Wi-Fi network, and would appreciate any assistance in resolving this matter.
- Are you getting any error message? If so can you please share the screen shot?
Cause 1: Port 445 is blocked: Refer to the suggestion mentioned in this article
Cause 2: If you have ever been blocked using Azure Files due to your ISP's port 445, you can setup a Point to Site VPN to your Azure Files. Refer to the suggestions mentioned in the GitHub article Check if your firewall or ISP is blocking port 445, use the AzFileDiagnostics tool or Test-NetConnection cmdlet.
