Indeed, your node seems to not sync.
When a node does not sync at all, it’s most likely an issue with DNS: your ISP may be filtering DNS queries or may forbid DNSSEC.
Can you check DNS problem with Algorand Server on Ubuntu 20.04 ?
Disabling DNSSEC is not ideal at all from a security point of view but may be the only options if your ISP does not allow it.
If this is not the issue, please post goal version -v, as well as the full node.log on for example a github gist. Please also check that:
- you are using a fast enough SSD
- you have at least 4GB of RAM, ideally 8GB
