Resolved - the long way: I restored an backup image. The 13.2.18 update was prepared but not installed. I went into Eset advanced settings and disabled Protocol Filtering*. Then uninstalled Eset and rebooted. Installed 13.2.18 using the offline installer and internet is working again.
*Could not do this with a fresh install of 13.2.18 because you can't get into settings without registering and you can't register without internet. You can't even activate evaluation without internet.
Not happy Eset.
