Hello @dsgnweblog,
My colleague advised you of how to disable the IP login restriction for everyone, so you can then successfully login to your backend. However, this could be also achieved via wp-cli:
wp sg login-access remove IP – removes IP from the whitelisted ones
wp sg login-access remove all – removes all of the whitelisted IP addresses
If you would like to check all whitelisted IP addresses or add an additional IP, you can use:
wp sg login-access add IP – allows only specific IP(s) to access the backend of the website
wp sg login-access list all – lists the whitelisted IP addresses
However, I would recommend you to double check your IP address, for example via:
https://icanhazip.com/
In case, your website is hosted at Siteground, you can also anytime submit a support ticket in your Client Area there and we will be glad to assist you further.
Regards,
Vladimir
