Sending configurations...
ERROR: Only nop and sig tag can be recevied before authentication.
[SERVER] Service unavailable: Internal error !
Server is green, online and i do have credits. I tried many times in the past 6-8 hours with no luck. Internet access is not a problem, i can acess support server and download files from it without a problem.
