How best to connect from cellular remotely?


Currently, I have an SFTP connection to a local computer hard drive folder.

Using local Wi-Fi on my phone I have access, however using ONLY iPhone cellular connection remotely the favorite folder - does not fail connection and seems to connect however the window is black without showing any content. (if I add local wifi - then it works and shows content)

Is there a proper procedure to be able to View content from cellular Remote connection (no wifi) on the iPhone?
