We have seen a rise in the number of people reporting issues automatically updating Gravity Forms, downloading or updating Gravity Forms add-ons from within their WordPress Dashboard. Upon investigation, we have discovered that the issue is typically due to a shared IP address being blacklisted by one of a number of Internet security firms.
This is a common problem with shared web hosts. Unlike most VPS and dedicated solutions, shared web hosts will share an IP address across multiple customers. If one customer does something malicious (intentionally or unintentionally) he can get that IP address blacklisted by one or more internet security providers. In other words, one user of a shared IP address can easily ruin things for all users of that shared IP address.
To be clear, this can also happen on VPS and dedicated solutions. You can accidentally get your IP address blacklisted, or the previous user of that IP address may have gotten it blacklisted. But it is much more common with shared web hosts that use shared IP addresses.
