Hi Shaon,
unfortunately it is not possible to provide even temporary access to the server and the wp backend due to harsh security regulations. login onto the server itself – and thus the companies intranet – requires a secured physical token based vpn connection.
We did set a host entry for wpdownloadmanager.com and poited it to localhost, so the ajax-request does not wait for timeout anymore but fails with a 404 immediatly. This does solve the problem of the overall slow backend, but still wont change the problem with the handling of the license key i guess.
best regards,
lars
