Please advise if I am on the right track, thanks:
I typed in my problem in ChatGPT, it responds was that my server cannot connect to the Docker image registry. it suggested:
1. check network connection
2. proxy or firewall issues
3. DNS configuration
4. Docker Daemon restart
5. Docker Hub Status
6. Docker Network configuration
7. Pull the image manually.
Since I am able to access the webGUI through computers on the network, that eliminates network connection issue. So 1 is out.
It then stated that network connectivity for Docker can be separate from general network connectivity. It's possible that Docker might have specific network configuration issues. It recommended checking the Docker network configuration and attempt to pull a Docker image manually.
So, I tried to use the command: docker pull netdata/netdata:latest in terminal, it said network is unreachable.
I then mentioned that during Unraid installation, the os automatically downloaded Community Applications and Unraid Connect.
It responded: That does indicate that the server has the ability to connect to external resources, including the Unraid community application repository. The error message encountered when trying to install apps through Docker suggests there might be an issue specific to Docker's network configuration.
I then went into Settings->Docker, it showed "No Docker containers installed." It then suggested these troubleshooting steps:
1. Proxy or Firewall
2. DNS Configuration
3. Router and Port Forwarding
4. Software updates
5. Community support
Since this is a new installation, that rules out 4. The servers is connected to a TP-Link mesh network which showed:
IP Address: 192.168.1.101
Subnet Mask: 255.255.255.0
Default Gateway: 192.168.1.1
Primary DNS: 192.168.1.1
Then I checked the Settings->Networks, at the bottom of the page, there's a routing table:
PROTOCOL ROUTE GATEWAY METRIC DELETE
IPv4 Default 192.168.68.1 via br0 1
The gateways do not match. Is that the problem? How do I change it? Or, am I even in the right direction? Please help, thanks.
