But, when link to smsc is up, client is connect to it succecfully.
How to fix bug with exception?

naz has not been tested on windows, we only run the test suite on linux;

naz/.github/workflows/ci.yml

Line 68 in 944c3a3

runs-on: ubuntu-18.04

you are going to have better luck if you try out naz on linux

[Slavix72]

ok. I will test it under ubuntu 18.04 and python 3.8.0
