Don't get auth code in telegram

[JackCat1]

Code that causes the issue

tg_ses = TELETHON_DATA_FIELD + str(self.instance.pk)
client = TelegramClient(tg_ses, TELEGRAM_API_ID, TELEGRAM_API_HASH)
await client.connect()

if await client.is_user_authorized():
await client.disconnect()
return {'status':'is_auth'}
phone_hash = ''
try:
send_phone = await client.send_code_request(phone)

if send_phone.phone_code_hash:
    phone_hash = send_phone.phone_code_hash                

except errors.RPCError as e:
return {'status':'error', 'msg':e.message}
except Exception as e:
return {'status':'error', 'msg':'Авторизация не возможна'}
await client.disconnect()
return {'status':'OK', 'phone_code_hash':phone_hash}

Expected behavior

I'd like auth in TG. I do client.send_code_request(phone) and get auth code

Actual behavior

I'd like auth in TG. I do client.send_code_request(phone) and get "phone_code_hash" But code in telegram doesn't come. It happens sometimes. Especially, I often get this behavior in the evening. Has anyone experienced this?

Checklist

• The error is in the library's code, and not in my own.
• I have searched for this issue before posting it and there isn't an open duplicate.
• I ran pip install -U https://github.com/LonamiWebs/Telethon/archive/v1.zip and triggered the bug in the latest version.

This behaviour likely happens from Telegram's side, and not Telethon, and therefore, there's probably nothing to fix in the library itself.

Do you know why this happens? Have you encountered this behavior before?
