New links when creating a flask

I made a telegram bot, decided to support its work with a flask, but when the link changed its appearance from name.username.replit.com on replit.dev, an error began to pop up in services like uptimerobot (503) and the bot simply turns off

yes, that’s because of a new update where repl.co links don’t work anymore. now you get a temporary replit.dev link and your repl turns off after you leave the replit ide. you can deploy the repl and your bot will stay up.
