This version of the script fixes the problem that the correct seeding time is calculated.

Hey,

Thnx for the script, could you help variable for authentication?

I try:
TRANS_HOST="10.0.1.5:5012 --auth user:pass"

Log:
[2021-11-20 08:57:02.047] transmission-remote: (http://[10.0.1.5:5012 --auth user:pass]:9091/transmission/rpc/) URL using bad/illegal format or missing URL

Don't know where the 9091 is coming from

I changed the script.... see if this helps for you!!

@marc0janssen Thank you very much! The script is working now :D

Great to hear Hugo
