Does the cheapest option (Comodo PositiveSSL) work?

Answer 1

Yes, it will. Just a couple of weeks ago I bought Comodo PositiveSSL from one of the partners for 10.95 USD for three years (!) for similar purposes. The bot in Telegram has been successfully raised. The only thing is that when installing a certificate for hosting, you should not forget about the chain of intermediate certificates. Otherwise, you will not see any errors in Telegram, but the bot will not respond. Best of all, after installing an SSL certificate, check the correctness of its installation on specialized services.

Until I purchased GlobalSign DomainSSL (the cheapest one I could find), I used the trick with hosting bot files on heroku. Here is a detailed guide: blizzy.ru/telegram/razmesaem-bota-na-platforme-heroku
