I have the exact same problem since a couple of days ago. Never had this issue before and I didn't change anything in my setup, no OS updates and obviously no application update (since there are no new versions of deluge for mac since forever). Anyone? Thanks! edit: I temporarily "fixed" ...

Any one can help me ?

Sometimes the error occurs as soon as the speed reaches 99.99%, and then the error continues. No matter how many times I click resume, the error always occurs as soon as the speed reaches 99.99%
I downloaded 25 torrents, 11 of them went wrong.

Hello, I am using deluge version 1.3.15. My system version is mac OS 10.15.3. When I download the seed, an error always appears, and it seems to appear randomly.
