This seems to be a backend error. Could you provide the backend logs?

[StroepWafel]

sure, where are they located if i'm running with docker? do they output to a specific location or log with docker?

docker logs metube or whatever your container name

[StroepWafel]

ah ok, i'll have a look as soon as i get home (roughly 3 hrs)

[StroepWafel]

sorry, i clean forgot to do this! reading the log i can see it says:

ERROR: unable to write data: [Errno 28] No space left on device
ERROR: Unable to download video: [Errno 28] No space left on device

but there definitely is space, so thats weird it works now, so maybe it is an issue with it not fully deleting the binned files (even though my docker compose has DELETE_FILE_ON_TRASHCAN set to true)

[StroepWafel]

nevermind, it stopped working AGAIN, even after not touching it for a week and having deleted all the files, my PVS server says there is available storage so im kinda confused
