1. Check Network and Internet Connectivity<\/h3>
The first thing you need to do is check and ensure that you have a stable network and internet connection. For this,<\/p>

- Open a web browser window and then visit any website to check if the internet is available and working.<\/li>\n\n\n\n
- Check the internet stability and reliability by visiting Fast.com<\/a>.<\/li>\n\n\n\n

- In case the internet is not stable, you can try to restart your router or reach out to your service provider for more help.<\/li>\n<\/ul>
2. Check Email Server Status<\/h3>
You can check whether your mailbox server is online or not. You can do this by visiting the web app URL and entering your login credentials.
