hi, so i have NPL license, and the server has going for 8 months already.

i know how to filter and enable sending server info to server list stuff,

but lately my server is not showing in the server list, like every 2 hour its gone for 1 hour then showing up again,
for 8 months this kind of problem only showing few times in a month, but now is like. everyday

sorry for my bad english but any idea to keep my server on the list?
