Make sure the Firewall setting is low/minimum.

Upgrade Internet Explorer browser to at least IE11, which allows Windows to meet required security standards. You should do this even if you do not use Internet Explorer as your primary browser.

Upgrade Internet Explorer browser to at least IE11, which allows Windows to meet required security standards. You should do this even if you do not use Internet Explorer as your primary browser.
Note: Service Pack 2 required.
Windows XP
Use 8x8 Work for Web via any Internet browser except Internet Explorer (e.g., Firefox, Chrome, Safari, etc.).
Check TLS in IE
Navigate to Internet Options in IE and check if TLS 1.1 and 1.2 is enabled. See screenshot below.
Cause
Assuming your computer or network's ability to solidly access the Internet is established, this is likely due to the security requirements in the latest edition of the 8x8 Work for Desktop application. On your computer, at least one of the following is causing the issue:
- Internet Explorer may not yet be upgraded to version 11, which allows Windows to meet the required security standards.
- You are not running a version of Windows that is at least Windows Vista with Service Pack 2 or later (e.g., running Windows XP).
