Can you see the cert expiry date on the dashboard?
It happens when it is failed to retrive the cert:

Can confirm, uptime kuma stopped exporting TLS cert expiry date since the update. Also i can no longer find it in the dashboard either
@louislam on the dashboard the expiry date is also not shown, but only for the http(s) monitors for my keyword monitors it’s shown correctly
Can confirm the same behaviour. Also expiry date on dashboard is gone. It was working yesterday before the upgrade.
Below the beginning of the output of the metrics page.
# HELP monitor_cert_days_remaining The number of days remaining until the certificate expires
# TYPE monitor_cert_days_remaining gauge
# HELP monitor_cert_is_valid Is the certificate still valid? (1 = Yes, 0= No)
# TYPE monitor_cert_is_valid gauge
monitor_cert_is_valid{monitor_name="
