File load error for "filename" Failed to fetch

Hello, I’m running jupyterlab in a GCP VM instance that runs as a service that is started with the command /home/ubuntu/anaconda3/bin/python3.9 /home/ubuntu/anaconda3/bin/jupyter-lab --ip --port 8888 --no-browser --allow-root

It has worked perfectly so far but today is giving me the error “File load error for ‘filename’ Failed to fetch” if I try to open most of my files (python files, noteboooks, images, etc). Already tried restarting the service and checking the log to see if any error message pops up when I try to open a file but nothing shows up.

UPDATE: Was using Chrome as browser, this stopped happening when using Firefox.
