Via my telegram bot I have to check if the user who texting the bot is in my telegram channel or not, I tried:
user_id = event.message.peer_id.user_id #user's id
async for i in bot.iter_participants(mychannelID, filter=ChannelParticipantsRecent):
if user_id != i.id:
status = False
else:
status = True
break
it worked only on my localhost, but on my Linux server it results an error:
Traceback (most recent call last):

I have already read entities.html as mentioned, but nothing is working.
Also I tried:
result = await bot(functions.channels.GetParticipantsRequest(
channel='username',
filter=types.ChannelParticipantsRecent(),
offset=42,
limit=20,
hash=0
))
if user_id not in result:

but I keep getting TypeError: argument of type 'ChannelParticipants' is not iterable
It turns out that I had to re-add my bot to the channel, because the bot lost access hash to the channel when I moved it to another device, since access hash is stored in the .session file and lost after the transfer.
