NethServer Version: 8
Module: Settings + Grafana
I have email notifications enabled.
Due to a rule in my firewall, the Let’s Encrypt certificate hasn’t been renewed and will expire on September 30.
Today I started receiving alerts (Grafana? NS8?), but I’m having these issues:
- The email arrives empty: no subject line, no message body, just mail headers.
- The message arrives every 5 minutes, and I can’t find a way to disable it
I logged into Grafana and saw an “Alert Rule” for “TLS certificates” with a red label that says “1 firing”; it’s
X-Mozilla-Status: 0001
X-Mozilla-Status2: 00000000
Return-Path: <ns8***@*****>

Thanks in advance. Regards
Edit 1: Is there a way to force the certificate update without breaking anything?
