[Help] TOS 5 Network Problem DNS Lookup Failed for Docker and Internet
Posted: 11 May 2025, 01:04
Hello,
I’m using TOS 5 and manually configured the network via the web interface, specifying a local DNS (192.168.1.1) and Google’s DNS (8.8.8.8). However, when trying to download a Docker image, I get the following error in Portainer:
*Error response from daemon: Get "https://registry-1.docker.io/v2/": dial tcp: lookup registry-1.docker.io: no such host*
The same error occurs when running docker pull via SSH. If I execute nslookup google.com, I see:
Server: 127.0.0.1
Address 1: 127.0.0.1 NAS
nslookup: can't resolve 'google.com'
How can I fix this?
