i am getting same error tryed two different virtual server

I think maybe try using an internal ip address not public ip address
internal IP maybe 192.168.100 and 192.168.200 up to your server (maybe 10.10.0.100 and 10.10.0.200)
some cloud server has local network config (Digitalocean Linode Vultr) try use it before use internal ip address
if used at home local network maybe use ip address at the same router (internal ip address)

TypeError: private_value must be an integer type.

from OP maybe the problem is from the python version try to test on a different python version to solve a problem
recommend with python 3.7 try this

how to run server mode?

pc 1 ip 35.221.30.146
from pc1 i run ./kangaroo -w save.work -wi 300 -o result.txt -s -d 36 in.txt


and pc2:
Kangaroo.exe -w kang.work -wi 300 -c 35.221.30.146
Kangaroo v2.2
Number of CPU thread: 4
Cannot connect to server: 35.221.30.146
Cannot connect to host: Connection timed out

I guess you are using windows 10 or any Microsoft windows
try to check your firewall, I think the firewall is block on your server
just try to add Kangaroo.exe to the firewall allow to access
