Teku client lost all peers and no new peers until restart

Description

Im trying to stake with teku, latest version teku-21.9.1

Acceptance Criteria

It works

Steps to Reproduce (Bug)

I run teku as expected

title "teku pyrmont eth-goerli.alchemyapi"
set eth_svc=https://eth-goerli.alchemyapi.io/v2/secretSessionKey
set JAVA_HOME=C:\Java\openjdk-16.0.1
bin/teku.bat --network=pyrmont --eth1-endpoint=%eth_svc% --data-path test-data --p2p-nat-method=UPNP

Expected behavior: [What you expect to happen] I expect network to sync. It does not. Other clients like Prysm and Lighthouse works perfectly

Actual behavior: [What actually happens] Peer count goes down to zero and stop sync.

Frequency: [What percentage of the time does it occur?] 100%

Thanks for logging this. The log you’ve included is only the console output. Teku sends most of it’s log information to a log file by default which is in test-data\logs\teku.log if you could give us that log it would be very useful in helping to track down what’s going wrong here.
