Hi,
I have configured 2 nodes, one master and one slave, with this step :

https://www.uyuni-project.org/uyuni-docs/en/uyuni/administration/iss.html

when started the sync, have this issue :

I have print the variables with :

print("HOST:",self.host,self.port)
output is:
HOST: 443

host is null, on:
```
results = socket.getaddrinfo(self.host, self.port,
socket.AF_UNSPEC, socket.SOCK_STREAM)

if try to set the host with:

`self.host="XXXXXXXXXXX"`

the command work.

Could you help me please ?

Thanks for your help request. But this is the Uyuni documentation issue board. For help, can you please try one of the options listed at https://www.uyuni-project.org/pages/contact.html (see Github discussions or Gitter chat channels).
It looks as if something is not properly configured with your name service (DNS).
