Can anyone in the forum tell me what that error message is? I subscribe for managed hosting of DDNs and it was working fine about 4 months allowing me to access remotely on the web. But now that is the error medssage. No-Ip could not resolve the issue. They blame the DVR. ISP have no clue why it is happening even after configuering the router. Any help is appreciated. However, I can access the DVR over LAN. I have Windows 7 OS.
