How to stop a while loop in Discord.py - discord

Question

I have made a Discord Bot that pings members(spam Bot). It uses a while loop. It automatically stops in a few hours(IDK Why But probably because the host I use resets the connection after a few hours).
I wanna make a command so that the bot stops pinging members but still be online. Basically I wanna end the while loop I use. Can anyone help me?
import discord
from keep_alive import keep_alive
client = discord.Client()
roleid = os.environ["#PingersRoleID"]
CategoryID = os.environ["PingsCategoryID"]
PingChannels = [
"ping1",
"ping2",
"ping3",
"ping4",
"ping5",
"ping6",
"ping7",
"ping8",
"ping9",
"ping10",
]
PingBotToken = os.environ["PingBotToken"]
#client.event
async def on_ready():
print("{0.user} has joined the chat".format(client))
#client.event
async def on_message(message):
username = str(message.author).split('#')[0]
user_message = str(message.content)
channel = str(message.channel.name)
# guild = client.get_guild(CategoryID)
print("{} sent {} in {}".format(username, user_message, channel))
if user_message.lower() == "!activatepings":
for _ in PingChannels:
if message.channel.name == str(_):
while True:
await message.channel.send("<#&{}>".format(roleid))
keep_alive()
client.run("...")

You can use a task that can be started and canceled at any time:
from discord.ext import tasks
#client.tasks(seconds=3600) #set to any amount
async def ping_task():
for channel in client.get_all_channels():
if channel.name in PingChannels:
await channel.send("<#&{}>".format(roleid))
#client.event
async def on_message(message):
username = str(message.author).split('#')[0]
user_message = str(message.content)
channel = str(message.channel.name)
# guild = client.get_guild(CategoryID)
print("{} sent {} in {}".format(username, user_message, channel))
if user_message.lower() == "!activatepings":
for _ in PingChannels:
if message.channel.name == str(_):
ping_task.start() #The task starts here
#client.command()
async def someCommand(ctx):
ping_task.cancel() #The task ends with this command
You can find an example of how to use tasks here: https://github.com/Rapptz/discord.py/blob/v2.0.0/examples/background_task.py

#client.event
async def on_message(message):
username = str(message.author).split('#')[0]
user_message = str(message.content)
channel = str(message.channel.name)
# guild = client.get_guild(CategoryID)
print("{} sent {} in {}".format(username, user_message, channel))
if user_message.lower() == "!activatepings":
for _ in PingChannels:
if message.channel.name == str(_):
while True:
if message.content == "STOP": ## replace it with the command you want to stop the bot
break
else:
await message.channel.send("<#&{}>".format(roleid))
