My node stopped working

I have a 2 months old month and today i realised is not working i cant acces by the ip an port to the web dashboard and when i type the comand to see the dashboard at the rpi it says that error.
pi@raspberrypi:~ $ docker exec -it storagenode /app/
2020-09-06T18:39:56.155Z INFO Configuration loaded {“Location”: “/app/config/config.yaml”}

error context cancelled

Try this checklist

yes the port is open ive checked at open port tool webpage and its open and the ip are correct

Can you show your docker run command ? You can remove any personal info from it.

docker run -d --restart unless-stopped --stop-timeout 300 -p 28967:28967 -p -e WALLET=“0” -e EMAIL="" -e ADDRESS=“213:28967” -e STORAGE=“900GB” --mount type=bind,source="/home/pi/storagenode",destination=/app/identity --mount type=bind,source="/mnt/storj",destination=/app/config --name storagenode storjlabs/storagenode:latest

this is the command but the node have been working ok for two month

Show output of following command.

df -h

You are keeping only 16G free which is not ideal considering SNOs are recommended to allocate only 90% of free space.

So if I reduce the storage I will work?

Do you see errors in your logs?
