Since some time I have the following error in the logs:

Any idea how to fix it?

Have you checked that your cookies.txt file is valid and up to date?

Virusmater commented 5 months ago

Yeah, after regenerating cookies it worked out. Any idea how often they are set to expire?

meeb commented 5 months ago

bandcampsync will automatically refresh your cookies.txt when it runs so providing you run the script periodically (or automatically on a timer via the Docker container for example) they generally shouldn't expire. If you only run the script occasionally then no idea it's up to Bandcamp.

This is similar to a question of "how long will I remain logged into a website if I close my browser?". Bandcamp generally seem to set cookies with an expiry of between 30 and 45 or so days but that's no guarantee that's now long they will remain valid if you don't refresh them. They can always force-expire your session token stored in the cookies although I've never seen that happen myself.

However, if you do see that error randomly then refreshing your cookies should fix it so it's not a major issue.

I'll close this for now. Feel free to comment if you continue to have issues.
