The algorithm I'm using is daggerhashimoto. At first I thought this was because of my country blocking Bitcoin mining or something, but it doesn't work even if I'm using a VPN (vpnbook.com/freevpn). Here's how the excavator console looks like. As you can see, the hashing speed stays at 0 H/s, and it's not connecting at all:

And I did leave my laptop mining overnight, but the speed never passed 0 H/s, so this has nothing to do with me not waiting long enough for it to connect.
