Hi JitteryCoyote63 ,
Did this error appear after some change to the deployment?

Yes, but I am not certain how: I just deleted the /data folder and restarted the server

it worked for the other folder, so I assume yes --> I archived the /opt/trains/data/mongo, sent the archive via scp, unarchived, updated the rights and now it works

Follow ths installation instructions, recreate the folders yourself and set the correct ownder and permissions before starting the server again

Your problem is you didn't set the correct permissions for the new directory (as specified in the installation instructions). sudo chown -R 1000:1000 <trains-data-folder>

Did you set the required permissions on the new copied directory?
