The second step to troubleshoot is to check the browser settings and compatibility.
You can do this by clearing browser cache and cookies, disabling browser extensions or plugins, or updating browser to the latest version.
You can also try to use a different browser, such as Chrome, Firefox, Safari, or Edge, and see if the web application works on them.
If it does, then the problem may be with original browser configuration or compatibility.
You can try to reset browser settings or check the browser console for errors.
