Slow torrent upload speed (linux iso)

Hey everyone,
I just received my fizz modem. I did a speed test for torents by downloading the ubuntu iso torrent. Download speed is good (10 MB/s), but upload sped is about 6 KB/s.
-The fizz modem is port forwarding a port in the 50 000 range to my desktop computer.
-My qbitorrent software is listeting on the same port.
- I disabled all windows 10 firewalls.
- https://www.yougetsignal.com/tools/open-ports/ says my port is open.
Any idea?
cheers
