Legacy Network announce

Hi everyone,

I'm currently running an open.mp GTA server on Windows Server. The server starts and functions correctly, but I'm encountering an issue with announcing the server to the open.mp list.
 Here is the relevant portion of my server log:


Legacy Network started on .....:7777.
[2024-07-07T20:25:27+0200] [Info] Couldn't announce legacy network to open.mp list.
[2024-07-07T20:25:27+0200] [Info]      [HTTP Client Error] Status: 10

Everything else works perfectly, but the server doesn't appear on the open.mp list.
