Hi there

We have an Apigee Edge 4.50 platform on-premise, working fine, but today it is throwing errors inrouter system log component, related with handshake.

Searching I did not find anything like it. Any ideas?

This is the error:

cat /opt/apigee/var/log/edge-router/logs/system.log

...

2021-08-24 13:03:09,680 RPCClientClientProtocolChildGroup-RPC-0 ERROR RPC - ClientHandshakeHandler.closeInvalid() : Received invalid handshake. Closing socket.

Is your Management server reporting issues connecting to your router? If not this is probably indicative of port scanning / health monitoring and not necessarily a problem.
