PC Can’t connect online

Hello, I recently bought BF2 on my pc so I could finally play online, but every time I try to join an online match, it goes to the loading screen, but than I get error code 201 or 216, both saying the connection is lost, it’s not my router or my internet connection, because every other online game has been fine and worked perfectly, I have restarted my connection and router multiple times anyways, I don’t know what else to try. Other online games work just fine
