Hello,
Thank you for your message.
Before we can continue with further troubleshooting, please make sure that you've updated all your remote Hosts to the latest version
7.1.7.0 since outdated Host version can easily be the factor that's causing the issue.
Please note that if you can't update your Host remotely for some reason, you can always update it manually as well. In order to do so, simply download Host installer from our
Download page and run it on the Host machine - this will automatically update Host and preserve its existing settings.
Let us know if the issue persists even after your remote Hosts are updated to the latest version.
