Dash Callbacks Firing Locally But Not When Run On Server

I have a Dash app that is running on local without any error. However when i run on the development server it is giving the error ’
Callback failed: the server did not respond.’

The page is loading in the server but the components which will be initialized by call backs are not working.

I am using flask server. I found the topic with similar issue:

In this topic, the server is NGINX and the solution was to increase server maximum entity size.

Is this can be issue in flask server? I couldn’t find any config parameter related to maximum entity in Dash.
Please help.

Did you solve this issue? I meet exactly same problem that everything run perfectly at local, but suddenly those dynamic callbacks stop to run on server (EC2 instance) and saying server not respond.
