I’ve recently tested and deployed a flask app as the minusthemiddleman website. All of the functions tested and worked in the sandbox by multiple testing methods before deployment to nginx and uwsgi in production. For some reason page 2 of the search function causes a resource problem in app as deployed. I’ve had a chance to monitor the redis directly using $redis-cli monitor and check my pip list to make everything is installed in production correctly.
The specific error is:
Internal Server Error
The server encountered an internal error and was unable to complete your request. Either the server is overloaded or there is an error in the application.
Does anybody have ideas as to why this is malfunctioning? Thanks,

I am new to NameCheap and I need help deploying a Django application. I just tried installing python on Namecheap's Cpanel using Python 3.7.12 with the desired Application URL, but I get the Error 503. Service Unavailable when I visit the Application URL after creating the python app. From the resources I have seen, I am supposed to get a python signification that the python app works and not an error. Thanks in advance.
python app setup on Namecheap's Cpanel
error page when i visit the application's Url
In my experience, Why does it appear?
The Webserver is currently unable to handle the HTTP request due to a temporary overloading or maintenance of the server.
Also among reasons can be:
inodes/disk overusage
irrelevant php.ini/htaccess directives
incorrect PHP version used
lack of memory
Solution:
Switch PHP versions;
Check disk space and inodes usage, etc.;
Check error logs and the latest error messages to find which script, plugin, etc. causes the issue;
ensure the server is up and running.
I am deploying my python Flask app in nginx server using gunicorn in Ubuntu. I am using mongodb. I have followed the steps from this https://medium.com/faun/deploy-flask-app-with-nginx-using-gunicorn-7fda4f50066a. Everything is working fine. I am able to get the response using GET method. But when I use POST method to insert into db it throws server overload error, internal server error. The code was working fine in development mode. This problem happened only when i moved the code to production.
I have deployed NLP project on Heroku server. If I am going to test the webapp by entering the fields, then I get INTERNAL SERVER ERROR:
The server encountered an internal error and was unable to complete your request.
Either the server is overloaded or there is an error in the application.
This app is successfully running on localhost. I don't know what happens after deployment.
Can anyone help?
Here is the screen shot of build
[
Here is the code of app.py file
This is the code of spam_classifier.py
These are requirements which I put on requirements.txt
It seems like your build got successfully deployed but you are getting the internal server error while you are consuming the API.So you will have to check the application log instead of the build log. To see that, in the heroku dashboard go to more>>logs. For every request that you make, you will be able to see the logs and hence the runtime errors if there are any.
Few other suggestions
You don't need spam_classifier.py in your file system on the deployed environment as you are loading the trained model from the pickle file.
Make sure that you have pushed the pickle files along with the code. I suggest that you use amazon s3 to store and load those kind of files
If you check the Application Logs in heroku you will find this error "Error R14 (Memory quota exceeded)" due to which you are getting the Internal Server Error after deploying the project on Heroku.
This is the first time I've developed a web app using Django and one of my first major attempts at programming.
I'm trying to deploy my project to the django test server- http://127.0.0.1:8000/ -but I get an error that says the connection is refused. I've looked through Django's documentation and and other websites about django deployment but I'm at a loss on how to troubleshoot this error.
If someone can recommend a way for me to deploy django locally so I can test my web app using django test server or recommend another deployment service that is easy for new programmers to use that would be very appreciated.
edit: After doing what Ojas Kale had suggested I still am at a loss on what the possible issue or issues that are causing this error.

i create simple hello world app using this tutorial

Error Response: [13] Timed out when starting VMs. It's possible that
the application code is unhealthy. (0/2 ready, 2 still deploying).
This error means that your application failed to start up correctly ("It's possible that the application code is unhealthy.").
Managed VMs rely on your application responding to "health checks" in order to determine when to send traffic to that version of your application. These "health checks" are an HTTP endpoint that the Managed VM infrastructure will check frequently for an "all good" response.
The getting-started tutorial contains working code, so it's possible that you introduced a typo or error in the file structure. Check http://console.developers.google.com/ and navigate to the "Logging" section to check your application logs for clues as to what the issue might be.
