Alert Slack notification not working behind proxy

[biperol]

Hi guys,

I want to run alert notification on Slack channel, but server is on corporate network and there is requirement to set proxy.

I already set proxy on network/global configuration and run setenv for https https in root console. I'm able to send message to slack webhook via cURL in command line. But configured (all fields) Slack Alert service does not send any message to my channel after pressing "send test Alert".

There is no any error in logs (messages, debug, middleware)

Have you got any idea, what else I need to set to get this to work ?

Hi Biperol,
Have you solved your issue? I'm experiencing the same one on my truenas installation: through postman, the webhook is working well and the displatched message is displayed on slack. Unfortunately, trying to use the same webhook in truenas, Failed sending test alert! message is displayed and nothing is reported in the logs.

Someone has any idea?

Thanks
