This has been discussed (at length) here: #946
It's been fixed in upstream, just not released yet. Are you using the last release? And if so, can you try with the current master?

@jgromes: I used the latest release (6.4.2). Now I pulled the current master and get the same error:

Based on the discussion you mentioned I tried again with joinDr of 3:
state = node.beginOTAA(joinEUI, devEUI, nwkKey, appKey, 3);
Now it seems to attempt a join request with SF 9, reaches a timeout, and then fails in a second attempt with SF 12.
I am not sure if this is expected behavior (as the SF 9 request timed out).

Any idea what the problem could be?

I see now that TTN actually receives (at least some) of the join requests. The first one appeared ok (even though I did not notice any change in the RadioLib debug output). Since then, however, I get the error "DevNonce is too small" in TTN console. I tried to reset DevNonce in TTN, but no change.

It looks like the original problem was resolved (TTN now obviously receives your join requests), so I will convert this to a discussion.
Based on the discussion you mentioned I tried again with joinDr of 3:
Setting appropriate DR is required, since LLCC68 only supports a subset of spreading factors.
I see now that TTN actually receives (at least some) of the join requests. The first one appeared ok (even though I did not notice any change in the RadioLib debug output).
So ... can you post the output? Was there a timeout, or did you receive the join accept message? Either way it might be worth it to wipe the persistent memory, and (temporarily) allow reusing dev nonces in TTN.
