How to connect Robert torrent for Purple I2P (i2pd)?

Question

bittorrent

On the developer's site, or more precisely, it says here that in order to use the Robert torrent (downloaded on the i2p network, on the developer's site ), you need to run i2pd with the -bobport=2728 parameter. However, Robert, downloaded from the specified address, writes to me that "BOB is not available! Check the I2P settings. Make sure BOB is up and running" I'm not sure if I'm doing everything right, but I followed the developer's recommendation above.
My actions:
Downloaded i2pd from the developer's site .
Downloaded Robert torrent using this same i2pd.
Closed i2pd and installed Robert
Started i2pd with -bobport=2728
Started Robert.
Gives an error message! What's wrong, who can tell? (I2P Daemon is not very common, as far as I understand, neither is Robert torrent, so all I know about their interaction is that concise information from the i2pd developer)
