address already in use 0.0.0.0:80

do you have some other web server running already on port 80?

[Nanashi-B]

nope only this one i have my domain on namebase with A record on namebase nameserver and NS, DS record on blockchain record

[pinheadmz]

well your operating system is telling you that port 80 is occupied.

also: [debug] (webserver) Webserver opened at host myipaddress -- that should be an IP address not a string:

--> node lib/handout.js 
[debug] (webserver) Webserver opened at host 123.201.32.45
[debug] (authns) Authoritative Nameserver opened for domain cool-domain.

[Nanashi-B]

i put my public ip address but i don't know why my port 80 is occupied i only have apache2 web server

apache is probably running on port 80, you'll need to shut that down to use handout, which runs its own web server.

[Nanashi-B]

hello i am retrying and i stop apache it's now okay for the ip address but i still have the error

Ok good. You're next issue is port 53 is protected so you may need to use sudo or setcap to allow handout (nodejs) to bind to that port

Same here , EADDRNOTAVAIL: address not available :53 on public ip in Oracle and same on my home lan . only worked for 0.0.0.0. Thanks
