Hi @santonic , i found the problem.
Both portal and gateway (in the same interface) must use the same certificate profile under authentication->certificate profile. If the portal has a certificate profile configured, but the gateway not, the request in the tls handshake is missing. I suppose that since the portal and gateway share the same web server daemon, the configuration must be consistent.
It seem also that if certificate is verified under the agent configuration "machine device check", is not enough to have the certificate profile under the portal data collection tab, the profile is needed also on the authentication tab.
Anyway, my case was that the gateway was not configured with the certificate profile.
Regards,
