Do not post passwords in online discussions! Since you already did that I advise changing the password for [email protected] account.

Do you see anything in prometheus-operator logs or in alertmanager logs?

[dinglu121]

thanks,i will change my password and check my pod.

hey，my kubernetes version is 1.20，using branch release-0.7.0，cause the configuration file is incorrect, this secret（alertmanager.yaml） cannot be loaded. After repeated modification, it can be loaded。But one parameter has not been loaded。"smtp_require_tls": "false" So can't receive mail。Can you tell me how to make it load。
