This can be circumvented using jupyter-lab (or jupyter notebook) running on the server and accessing it using a client machine. I presume you have already installed jupyter-lab (or jupyter-notebook) on server. Jupyter-lab is a better option as it comes with a file-navigator, spread-sheet viewer (faster than excell, reminds me of sublime text) and an image-viewer.
