Hi,
I have a metricbeat on debian. It has been a week since the metricbeat service stopped sending data.
The cause: ERROR [esclientleg] transport/logging.go:37 Error dialing x509: certificate signed by unknown authority
The server is not the problem, cause i got an other Metricbeat who works well.
If you know ho to fix it...thx

This is related to Certificates, the Certificate Authority.
