[SOLVED] can't resolve host Service not found

When I installed ModeSMixer2 on 64-bit DietPi Bullseye, It gave following error:

Jan 17 12:20:58 DietPi modesmixer2[468]: 2022-01-17 12:20:58.417  ERROR    inConnectId( can't resolve host Service not found

Radarbox24’s rbfeeder also failed on DietPi with following error message:

getaddrinfo: Servname not supported for ai_socktype
[2022-01-17 12:34:11]  Could not resolve host name specified in 'external_host'.

I solved this problem by installing package “netbase”.
After installation of “netbase”, both ModeSMixer2 and rbfeeder started working normally.

sudo apt update  
sudo apt install netbase  
sudo reboot
