Such errors still appears randomly and without visible causes. Maybe it will be better if gallery-dl does not stop, but just wait a pause and retry?

Should be fixed in d7bc4a2.
Retrying the same API call usually doesn't help here, only updating the GraphQL query hashes seens to work and for gallery-related calls this needs to happen rather often compared to the ones for user profiles.

Thanks, I just changed those hashes in 500px.py, and now it works fine.
