CWP -> CWP Migration can't list accounts in 2. step

I've used cwp migration several times. But this time I'm connecting origin server successfully , it isn't listing accounts. Screenshot:

I seems there is response. There is any error in console tab.


Origin CWP version: 0.9.8.762
New CWP version  : 0.9.8.763

I am having this same difficulty.

I am not getting the LOCK/UNLOCK option and can't list accounts.
