Problem with NR in Docker: no connection to the outside

UPDATE for the people with similiar problems:

I found this solution: https://www.problemsolvedtoo.com/2019/02/14/docker-dns-issue/

Just create a daemon.json file in /etc/docker/

sudo nano /etc/docker/daemon.json

enter

{
"dns": ["10.0.0.1","8.8.8.8"]
}

8.8.8.8 for Google's DNS

and

sudo service docker restart

worked for me fine. :slight_smile:

Thanks for reading, have a good xmas <3


Hi there

i need your help.

I got a new RPi4B and installed Nodered (NR) with IOTstack (along with Wireguard, Nextcloud, Influxdb, Grafana, Mariadb, Tasmota, Portainer).
For some reasons my telegram-bot stopped working (it did until yesterday, but i didnt changed anything today). I just get this error message:

"Error: EFATAL: Error: getaddrinfo EAI_AGAIN api.telegram.org api.telegram.org:443"

Interestingly, i get data from openweathermap.

In a post from 2019 it says this is a DNS problem. Unfortunately i dont have PiHole installed as the guy in the post back then. So there is no simple solution for me like he found.

This is probably more a Docker/IOTstack-problem then a node-red related one, i guess.

Any guesses where to start?

lovely wishes
Jonas
