the problem"Having issues getting kad-feeding, please create a tracker" always happens when the program begin the kad in the main.
but i'm sure i have log-in.
is that related to my internet connection unstable?
There's about a 95% chance that an unstable internet connection would cause that problem.
Most of the errors you received are a side effect of the program thinking you're logged out.
If you are logging in manually, and not through cookies, then your internet is most likely the problem.
