“abort sync, triggerSource=manual, error while syncing” on Storc

Hi all,
I am new to obsidian and recently I tried to use storj.io as my s3 storage.
at the beginning it was OKAY, everything works. But then I encounter error with message:

abort sync, triggerSource=manual, error while syncing

followed by request failed.

is it a problem with my obsidian setup or is it a problem with Storj?
Any solution/ideas?

Thank you
