The always-on task stops after a few seconds? I recommend adding some more logging to figure out where it's failing. Check out this help page: https://help.pythonanywhere.com/pages/AlwaysOnTasks#stuff-that-you-print-doesnt-appear-in-the-log

No, Always on task doesn't stops, it never starts. What I'm saying is, when I 'reload' my app in the 'Web' tab, it works, but just for a few seconds. Then it just send me to a page with the message: 'Internal Server Error'. If I reload it again, it works again. But with Always On tasks, it doesent works at all, it just says 'Starting'...
I checked out your always-on task, and it looks like it's trying to run a Flask app. You don't need to do that in order to run a website; when a website is configured on the "Web" page, it's started up right away, and if it's ever shut down, it will be started up again as soon as a request comes in. If you try to configure one as an always-on task, then a normally-configured Flask app will just start, exit, start again, exit again, and so on -- so on the "Tasks" page it will always look like it's starting, and the logs will just contain "Task preparing to start" because it will never log anything. So I recommend you just delete that always-on task, it's not doing anything useful.
Regarding internal server errors on your website -- check out the website's error log for that. There's a link to that on the "Web" page, and the most recent error will be at the bottom of the file.
Thanks for your answer. I checked the server errors and it says: "mysql.connector.errors.OperationalError: 2013 (HY000): Lost connection to MySQL server during query". How can I maintain my MySQL connection stable?
