It looks like you have the wrong dependencies for python 3.9

[brothercorvo]

Try again with 1.9.5 and Python 3.8, follow the instructions of the video https://www.youtube.com/watch?v=ot3PNY903ns&ab_channel=FreeTAKTeam

I've experienced the same issue with Python 3.9 and FTS 1.9.8. After some digging it looks like the version of eventlet has this as a known issue. In my test environment I updated eventlet to 0.30.0 and the issue went away. I have not noticed any abnormal behavior in FTS after doing so, and the error no longer appears.
