Hello,
I tried to configure Alerting in Grafana on my Ubuntu VM.
I edited /usr/share/grafana/conf/defaults.ini
Note: I censored the PW for the screenshot.
Then restarted grafana-server.service.
I configured a Notification Channel in Grafana.
But when I try to test it I get
If I look under Alert Rules I see
Execution Error: tsdb.HandleRequest() error parse “192.168.1.10:8086”: first path segment in URL cannot contain colon
Edit: after I changed my InfluxDB from 192.168.1.10:8086 to http://192.168.1.10:8086 I didn’t get this anymore but I still get the “Failed to send alert notifications” error.
Source: https://community.grafana.com/t/grafana-7-alerting-issue-error-tsdb-handlerequest-unsupported-protocol-scheme-influxdb/31226
at my Alert Rule.
Hope anyone can help.
Best regards Tobias
I also allowed less secure app access in Gmail.

The two errors are unrelated, though it sounds like you’ve fixed the InfluxDB query issue.
For the SMTP/emailing issue, there should be more details in your Grafana server log.
Yes InfluxDB issue is fixed.
Log entrys for SMTP issue:

I guess the issue should be clear based on the above messages? Grafana can’t establish a network connection to the SMTP server.
Sure, but if I try to ping the SMTP Server it works.
Do I have to configure anything else in Grafana? Any ideas?

Hm…not sure in that case. I do remember having issues connecting to Gmail’s SMTP server at some point in the past (not specifically from Grafana) - there appears to be some nuance regarding TLS and/or SSL depending on the port.
This is not particularly scientific, but you could try some combination of the following:
Comment out the cert_file and key_file options, given that you’re not using them (and I don’t think they should be necessary). Just to make sure Grafana isn’t doing something funny because the option is there but set to empty
Try to set a different startTLS_policy option
Try port 465 instead of 587 (SSL instead of TLS security)
Set skip_verify=false
Sorry I can’t really be of more help. Maybe someone out there has a “proven working” configuration for Gmail SMTP (we use AWS…)
Wrote the same instruction…then looked that yours has appeared.
Lie down, try not to cry, cry a lot, teehee
Yes, Tobias, try this and that should definitely help.
When I had problems with fetching gmail emails - changing port was the decision.

I got the same problem in the latest version 8.0.6 Have you solved it ?
I’m getting a timeout error when send an alert of Test email notification from Grafana. Used YUM repo installation for Grafana service on RHEL 8 (red hat linux server) and updated grafana.ini . Not using any docker images .
[smtp]:587
Tried with starttls = nostarttls option also in the same file but still getting the same error
