I tried to update a cpe. Cnut was stopped as from image. What problem can there be? Thank you

I'm not sure if this is the same error or not, but the problem I initially ran into trying to use CNUT with ePMPs was that I was running CNUT on a PC that was behind NAT, and the ePMP's need to be able to access the CNUT server. I moved CNUT to a&nbsp; server that wasn't NAT'd and it worked fine.

Also verify HTTP server used by CNUT operates on proper interface.

Then try to restart it.

Thank you.

I tried it with a epmp180 directly connected ethernet cable (IP: 192.168.0.2), but I have the same problem. I also tried to disable windows firewall. I think my problem is that I have not found a guide to set properly cpe epmp1000 and cnut together; where can I read up? Thank you
