With a bit of help from ChatGPT I found that it is the Docker’s Bridge network configuration or whatever that means that is the problem.

I’ve tried several fixes but so far without success. Haven’t tried this one yet:

 ![The image provides steps to manually reset Docker networking by stopping Docker, deleting the network directory, and restarting Docker. (Captioned by AI)](https://global.discourse-cdn.com/meta/original/4X/e/5/e/e5e27e6aa7ae47d284b9f557a935d5b31eb377c8.png)

Is this safe for a production environment? (even if it creates a short downtime)
