Login/password problems with fetchstats on bash

I tried to download the stats using fetchstats bash script on my MacOS machine. It always gives me a login/password failure.

My password is correct and I can see the stats online on the dashboard. I also added a echo for the username and password in the script and I see that the script does encode them using %hex letters so special characters should go through just fine.

Any other ideas what is going wrong?
