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 on, 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 links don’t work anymore. now you get a temporary link and your repl turns off after you leave the replit ide. you can deploy the repl and your bot will stay up.
