gaierror : [Errno -2] Name does not resolve

Looks to me you have a error in your hostname, or your dns server cant resolve your hostname for your mqtt server. Try the ip address for your mqtt server.

I always provide the IP address in these cases. I just had added the port 1880 at the end of the ip-address ;)

all good now .. works great!

thanks for the quick response and help

I have the same issue. Adding the port for the MQTT Listener after its IP address (...XX:PORT) did not fix it for me. I'm not sure what else to try. Ginlong-scraper runs on Docker on the same system my MQTT server runs (a Synology NAS). Does anyone else have this issue?
