Clients might "miss" a message

[WillNilges]

This morning, I heard LetMeIn doing a jingle, and there was a light on. I hit the button and went to go let the person in, but there was nobody there. Checking slack, the request had been sent well over 10 minutes ago. Something's fishy with that.

Mostly just a note for myself, this has also been occurring the other way around. The jingle will occur and the request will be over, but Slack randomly seems to not receive the timeout message.
