Netplay Troubleshooting

[Breezy Satina]

I haven't been able to find anything related to this issue no matter how much I look, so I thought I'd try asking here. Whenever I try to host a netplay session in Dolphin R6225, after queuing the ISOs I want to host, I go to start netplay and the box in the host tab is blank. I can't get the games to show up there for selection no matter what I try. I've tried re-downloading the emulator, re-downloading the ISOs, everything. Nothing works. Any help with this would be greatly appreciated.
