Flask+MySQL: :( Application Error

Question

Hello, I'm making a webapp with Flask and MySQL.
I deployed my webapp and it worked very well with Azure.
However, yesterday, suddenly this error is occurred.

:( Application Error
If you are the application administrator, you can access the diagnostic resources.

(There is no specific error logs or directions)

I checked

1. logs --> nothing was special
2. configurations --> added app setting
3. my python code --> It works well in local
4. git repository which is connected
5. and so on

But nothing is changed.
I searched a lot and some people said it might be because of SSL. I have not bonded the SSL file yet.
I wonder it is really because of SSL things because it worked well even though I didn't bind the SSL file to my webapp. But suddenly it became a problem? I'm not sure...
And should I make a custom domain? because this advice introduces that.

Please save me from this error...I can't figure out it:(

Answer 1

There could be issues with resources - mem, CPU, disk.

Did you check disk used or your chosen plan?

Hope this helps.
