After I deploy the node locally on testnet I can see the following error messages from the rosetta server, I have to manually add peer can resolve the issue

Sometimes I can see the following error messages from the rosetta server and the sync gets stuck

Discuss with @syuan100 and we think the root cause of the issues above is the seed issue.
