Grafana Failed to send alert notifications

1

Hello,
I have been trying to “Send Test” to try out the Grafana Alerting however I did not manage to make it work…

I followed the official documentation on Grafana’s website and this tutorial : Grafana Mail Alert Configuration. | techiescorner.in .

This is my configuration on Grafana:

2020-08-07-174542_1920x1080_scrot
2020-08-07-174542_1920x1080_scrot1920×1080 132 KB

Then in the configuration files I have the following for the configuration of SMTP other than that I did not change anything in the file:

2020-08-07-174801_1920x1080_scrot
2020-08-07-174801_1920x1080_scrot1920×1080 282 KB

After this, I restarted Grafana as asked by the tutorials using the command line.

However, when I try to “Send Test” I get the following error on Grafana: “Failed to send alert notifications”

So I looked in the log and go this:

t=2020-08-07T17:43:45+0100 lvl=info msg="Sending alert notification to" logger=alerting.notifier.email addresses=[lolasmith2406@gmail.com] singleEmail=true

I do not understand what my error is and what I should do to make it work. Can anyone please help me or if I need to add any additional information please let me know. Thank you

The Gmail hostname is smtp.gmail.com and not stmp

can you tell what might be the issue

My guess is that you have a space between host and the port number.

There should be no space after the colon between host and port for the host configuration setting:

[smtp]
enabled = true
host = smtp.myhost.org:2525

Is anyone getting a timeout error when sending Alerts or Test Notification from Grafana? I have Prometheus and Grafana service installed in our RHEL 8 server (linux red hat) and grafana using YUM repository installation. Not using any docker images. vi This is the file path: /etc/grafana/grafana.ini

[smtp]
enabled = true
host = **:587
user = ****
password = *****
skip_verify = false
from_address = noreply@.com
from_name = Grafana

Tried with starttls = nostarttls option also in the same file but still getting the same error ::: Can someone please help?
