500 Internal Server Error on atenahub.app.br (Morty server)

[talesaz]

Hello HelioHost Support Team,

I am hosting my Flask application under the domain atenahub.app.br on the Morty server.

Since the server maintenance that occurred yesterday, I have been experiencing frequent "500 Internal Server Error" responses. I checked my access logs and noticed several automated malicious bot requests (directory fuzzing/scanning for .env files).

I am not entirely sure if these 500 errors are simply my application breaking due to these bot attack attempts, or if it is a side effect of the recent server maintenance/movement. Could you please verify the server status and help me investigate the root cause?

Additionally, to make my backend more robust and mitigate these brute-force/scanning attempts, I plan to implement a rate limiter. Could you please install the Flask-Limiter Python library on my server environment?

Thank you for your time and assistance!

I have an additional request regarding my database on the Morty server.

I am trying to connect remotely to my MySQL database using HeidiSQL and my local Python environment for development purposes. However, I am consistently getting the following error:
Access denied for user 'talesaz_matrizhub00'@'2804:...' (using password: YES)

Here is what I have already checked and configured:

My credentials are 100% correct (I can access the database perfectly through phpMyAdmin in Plesk).

In Plesk > Databases > User Management, I have already set the Access Control to "Allow remote connections from any host".

Could you please verify if there is any server-side issue?

This database is related to matrizhub.heliohost.us

Thank you again for your time!

Your account was recently moved to the new morty server, did you update all of the references from morty.heliohost.org to morty2.heliohost.org?

Hi MoneyBroz,

Thank you for the update. Changing the hostname to morty2.heliohost.org fixed my remote database access via HeidiSQL.

However, the production site atenahub.app.br is still returning a 500 Internal Server Error even after updating the internal database connection strings.

Since my account was recently moved to the new server, The Python + Flask environment and WSGI configurations were fully preserved during the migration?

The WSGI restart/reload mechanism is functioning correctly for my account on morty2?

Thanks!
