find no peer after restart

[BomaxChen]

Our bsc fullnode encountered a 'Bsc extension Handshake failed' issue. After restarting the node, we are unable to find any peers. How can we resolve this?

Although 'Bsc extension Handshake failed' is en error log, it only indicates the remote peers is not BSC compatible and will it be rejected. It is common log, It should not block finding other good BSC peers.
Could you try update your nodeid by:

# replace <datadir> with your local data directory.
mv <datadir>/geth/nodekey mv <datadir>/geth/nodekey.bak
# restart your node, it will generate a new nodeid

See if it can help
