RPi Zero with RTC DS1307 - Remote I/O Error

EDIT: This problem is solved! the problem was a script running on the pi, which occupied the SCL pin (in my case a script listening for a shutdown button). So it was not able to read the rtc.

I'm currently following this tutorial to connect my Raspberry Pi Zero W running Jessie Lite to the RTC DS1307. The rtc is being recognized when running sudo i2cdetect -y 1 with "UU", so everything fine until this point. But when entering sudo hwclock -D -r I'm getting an error:

Error Message

Does anybody have any experience or hints with this error? I was researching for 1 1/2 day now, but could not find a working solution. Any help is appreciated.
