The problem is still ongoing. The reason for the data not coming after March 5th is that the Docker services on the application server (Linux) were restarted during that period, and I was unaware of this. Later, I was informed that the data was not coming from the application. When I checked the Elasticsearch service on the database server, I noticed it had stopped, so I restarted it. However, after that, I couldn't retrieve new data from the application. I made requests using curl, and the index is there, data is coming. Even after disabling the cache and making requests, data is still coming. There were no changes in the code, so I don't think the issue is there. It seems like the problem is more likely on the DevOps side.
