Your configuration is going to shut down the link as soon as a bpdu is received. That is probably fine if you never expect a bpdu (which is usually the case on a link to a server).

Now, I would just point that the bpdu is not the source of the loop. It's just an indicator that you have some unexpected bridging on the port.

If you had some bleeding of bpdus between your uplink, you probably also had a bleeding of user traffic -> and that's the loop. Looping back the bpdus will actually result in the spanning tree starting to block some ports (if you are running it on the path covered by the loop).
