Error encoding and sending metric family

Hi can someone help with this error?

pushgateway[32654]: ts=2023-07-07T09:33:39.589Z caller=main.go:60 level=error msg="error encoding and sending metric family: write tcp> write: broken pipe\n"

I’m trying to understand what is wrong here, tried to enable --log.level=debug on pushgateway but I don’t see any debug, only above message from syslog.

During such errors, there is gaps in Grafana
