I get the following error when running the script on Windows 10 using Python 3.8.1:
Traceback (most recent call last):
File "my\path\cf-ddns.py", line 29, in <module>
with open(config_file_name, 'r') as config_file:
FileNotFoundError: [Errno 2] No such file or directory: 'cf-ddns.conf'
The cf-ddns.conf file is located in the same directory as the Python file.
