Your Balancer license is limited by the number of “server xxxx” lines it finds in your config file.
The best way to see what Snapt would report is to run the following command:
cat haproxy.cfg|grep "server"
If you require more servers as your current license is not sufficient enough then simply visit your shop dashboard to upgrade your license, when upgrading a license you will not have to pay the full price as you just pay the difference from your current license.
If you are running a trial an need a few more servers, please feel free to contact us and let us know so that we can assist.
