Hi, i try to install discourse for the first time on the official way with the discourse-setup script… on an Arch VPS (testing purposes with a group) - which has a fresh nginx installation - i’ve stopped an deactivated it for now… to get a working built. The Script hangs on “Checking your domain Name…” - i’ve looked into the script and thats a call to “connect\_to\_port” - i guess he’s trying to connect to a 443 there… netcat is installed… if i enter for example “nc host 443” in the shell i get no output and nothing happends… i guess because the “outer” nginx is not running - so nothing is on this port… not sure what the script exactly does there. I’d also tried to skip that test - but it seems in the end - after the build - he’s trieing something similar - that has’nt worked either. So deleted everything and started now fresh… what can i do - to get this netcat connection test running ? Maybe that solves the other problems also… (Sorry for my horrible english… - i’m not a native speaker…) I’ve tried it again without netcap - the build ends up with this message… docker: Error response from daemon: driver failed programming external connectivity on endpoint app (80e0a31158301339ff7c9567079017bb795b1172ee47e1c6417c29acda3c699a): (iptables failed: iptables --wait -t nat -A DOCKER -p tcp -d 0/0 --dport 443 -j DNAT --to-destination 172.17.0.2:443 ! -i docker0: Warning: Extension tcp revision 0 not supported, missing kernel module?
