If when accessing a web application or your website, then find an error message like the following, then there are several things you should pay attention to.
- Check if your domain name is correct and there are no typos?
- Log in to your server and access the file manager, are your web files uploaded and placed in the proper folder/path?
- Make sure your domain's DNS resolver is to the correct IP address server.
Hope this helps with your problem.
