Alpha Vantage - "daily API rate limit reached" shown every day

Question

I am using Alpha Vantage API to fetch financials for some stocks from a Python Script. I could successfully use Alpha Vantage API initially to get financials data, but now, every single day I am getting the same error when trying to query the Alpha Vantage website:

2025-01-13 12:37:02,938 - WARNING - 'Alpha Vantage' Response: Thank you for using Alpha Vantage! Our standard API rate limit is 25 requests per day. Please subscribe to any of the premium plans at https://www.alphavantage.co/premium/ to instantly remove all daily rate limits.

Despite waiting for waiting more than 72h, I am still getting the same error on multiple machines.

I also tried with multiple API keys, but it did not help.

What could be the issue?
