Create description about your issue, and your actions to solve it.
I have some issue when I started gateway over local installed thingsboard. Following this guide https://thingsboard.io/docs/iot-gateway/getting-started/ , I download docker-compose.yaml file, and started gateway by command "docker compose up" in teminal.
I have got the following error :

I have found the issue, it was an issue with my firewall.
I have disabled a firewall for testing purposes and it is working.
