This notification results from a connection error. Due to an external cause there was no communication with the eBay servers.
Reasons most common for these errors are not working or faulty configured firewall programs which sometimes deny other applications to use the internet connection. Defined exceptions often don't work steadily.
If you use such a firewall program and a problem occurs you should delete releases for SchnapperPro and set them up anew.
To commune with the eBay servers SchnapperPro utilizes the http and https protocols via the 80 and 443 ports.
Components requiring an internet connection are
SchnapperMain.exe and
CommClient.exe
To check if all SchnapperPro components receive access to the internet please perform the connection check which is released by the keys Ctrl+F3.
