What is wrong with this HTTP script? Why won't it send a message?

I have made an HTTP script that sends a message to Discord. It is for a commission system. The player does get kicked after they click send, but the message doesn't send. I was wondering where I went wrong with this. I tried making it send just a small message, and it worked, but when I send this message, it doesn't. There are no output errors.

Server Script:

local webhook = "censored"
local remote = game.ReplicatedStorage.Send
local HTTP = game:GetService("HttpService")

function Fire(player, msg)
local payload = HTTP:JSONEncode({
content = msg,
username = player.Name.." - (#"..player.UserId..")"
})
HTTP:PostAsync(webhook, payload)
end

remote.OnServerEvent:Connect(Fire)

Local Script (in the button):

local remote = game.ReplicatedStorage.Send
local plr = game.Players.LocalPlayer
local need = script.Parent.Parent.QAA
local contact = script.Parent.Parent.QBA
local money = script.Parent.Parent.QCA
local skills = script.Parent.Parent.QDA

function Send()
local msg = "I need: "..need.Text..". You can contact me by: "..contact.Text..". I am willing to pay you: "..money.Text..". I want the skill level of my developer(s) to be: "..skills.Text.."."
remote:FireServer(msg)
plr:Kick("We will get back to you as soon as we can! Thank you for requesting!")
end

script.Parent.Activated:Connect(Send)
