Too many failed attempts
After 10 failed sign-ins in 5 minutes, the server refuses new sign-ins for a short time.
What you see
too many failed attempts: try again in 4 minutesWhy it occurs
10 sign-ins failed in 5 minutes.
The limit counts for the full server, not for each address. Thus it is possible that the failures are not yours.
How to repair it
Wait. The server accepts sign-ins again when the oldest failure is 5 minutes old.
If it occurs again and again
Another person tries to sign in. Keep the API on 127.0.0.1, and reach it through an SSH tunnel.
ssh -N -L 7878:127.0.0.1:7878 you@your-serverSee Security model.
