Hi @myworldz
It’s possible your Desktop ip address has been blocked by your website if you are running a security plugin such as Wordfence or iThemes Security.
This would explain why you can’t visit via Desktop but you can use a mobile connection (assuming your mobile connection is through mobile data or a different network and hence has a separate ip address).
If you can log into your website via your mobile then you should be able to check if your desktop ip address has been blocked and remove the block.
An easy way to check your desktop ip address is go to https://www.whatismyip.com.
An alternative option is to use a VPN so that you are assigned a new IP address that isn’t blocked.
One thing to test is whether other people outside of your local network can still access your public facing site. If so then you can relax a bit knowing that the site isn’t down, it’s just your individual connection being affected which will give you time to get in and sort it out.
