WARNING j.p.slack.StandardSlackService#postToSlack: Response Code: 404

[NattGlobal]

Our Slack notification plugin was seen working on the 19th of November 2024. Since then, it has been failing to send any slack notifications.

I've checked all the parameters you wrote under your README; they're all at default values.

I am not sure if you have any other suggestions or if there were any changes in the plugin that we ought to know.

The error seen on the console:
ERROR: Slack notification failed. See Jenkins logs for details.

and the error seen on the Jenkins log is what I've used as the title of this issue.

Try enabling more logging:

How have you configured the integration? Bot user mode or the legacy integration?
