DBC error: unknow reply: unable to complete request

I have been using the deathbycaptcha service perfectly for weeks, however, today I get the following error:
my credentials are ok, I have verified them several times, I have a balance in the platform and I have even recharged more credits, I have restarted my PC and nothing, I still get the message and it is not active, is it deathbycaptcha error or some GSA bug? any solution?
