Telegram Keeps Saying Too Many Attempts — How to Fix Login Block

I haven’t been able to log into my Telegram account for the past four days using my iPhone 15 Plus. Each time I try to sign in, I immediately get the error message:

“Too many attempts. Please try again later.”
and no verification code is ever sent to my number.

I’ve only tried logging in over Wi-Fi, and I’m using the latest version of the Telegram app. My account is registered with a Turkish phone number, and I also have a Telegram Premium subscription.

I’ve tried to reach Telegram support, but there seems to be no available help channel to contact directly.

I kindly request that this issue be resolved as soon as possible, so I can regain access to my account and use my subscription again.
