Content filtering is a common practice to ensure employees do not access restricted Internet content. In most cases, the filter only is set to prevent access to certain areas of the Internet that are restricted by your company's policies. However, if your company's content filtering software uses a web proxy, it can interfere with the ability of users to sign in to the Code42 console.

Recommended solution

If you suspect that content filtering may be the cause, add the Code42 console address to your content filtering software's allowlist. Doing so will ensure that users can access the Code42 console without interference from your company's content filtering software.
