Issues with the slack notifications on certain projects

Hello Everyone. I’ve been scouring the bug reports, reading logs and whatnot and can not figure out the issue I’m having with the Slack Notification service.

So the story goes, we have a couple hundred repos on a self hosted gitlab, and all of them have the same slack service configured, ie the same options, webhook URL and so forth.
