Zabbix 4.4.7 / Slack / CentOS 8

[devinacosta]

I am running a fresh installation of CentOS 8, and Installed Zabbix 4.4.7. I tried to use the new Slack Webhook that comes with 4.4.7, using the bot_token, however Zabbix is having an issue.
When Zabbix fires it gives error "Slack notification failed: channel_not_found". However I am using the correct channel, and I have look at Slack and I don't see any reason it would not be working.

I have enabled the bot_token parameter with a key liek "xoxb-xxxxxxx-xxxxxxxx-xxxxxxxx". Even when I try to do the Test of the Media, it fails.

I see there was this issue, so not sure if there is still some strange issue?

Any help appreciated, i think I may have to go back to the Script (old style).

So i ended up rebooting the host as I moved it to a new IP and then I realized it does actually send to Slack. The "TEST" for the Media Type just doesn't work period. So something is wrong with that functionality. However it did send updates to my Slack channel when i forced an event to happen.

Hi @devinacosta,

I am also getting the same error. I have tried including # format and without I also tried to send to the direct message using @username.

But it failed with the same error "Slack notification failed: channel_not_found".

I have followed the link.

Could you please let us know, how the issue resolved for you?
