Inkbunny now uses a 5.x.x.x address as its public IP address, so Hamachi will be in conflict with it.
This means if you have Hamachi installed, or ever had it installed but did not run a full uninstall, you may not be able to access Inkbunny or it may cause intermittent access problems.
Even though Hamachi updated to assign only 25.x.x.x addresses in current versions, it apparently still causes access issues to 5.x.x.x addresses such as Inkbunny uses.
Unfortunately we have no recommendations about how to fix the issue except to fully uninstall Hamachi using its own uninstall process. There may be configuration changes you can make in Hamachi to fix the problem but at this time we do not know of any.
Update: While we haven't had any reports of this that I'm aware of, Comodo's EasyVPN also used to use 5.x.x.x addresses, so it's also worth watching out for.
