CWP error after installation, I can access the root but always loading

Hi,
now i've been 8hours working to install CWP actually this is my very first time

Need your help 

always loading until RTO to access myipaddress:2030 or https://myipaddress:2031 ( just loading and no response at all )
buy when I access the root, there is no problem

Start again, from fresh, carefully reading the installation documentation.
I reinstalled a VPS three days ago, with zero issues (apart from the obvious CWP bugs mentioned in the forum).

do you know any tutorial that i can follow ? i've read many articles but still got the issue.
before i try using free server in alicloud and actually now i try using t2.small (Aws ec2) but still the same issue
so the issue comes from the way i install the CWP

hi whats your server's specs ?

when i post this, i'm using ECS Alicloud with vCpu 1 - memory 1GB, i got the issue as i said before

then i try using AWS
my server spec: t2.micro (Aws server ec2)
vCpu 1 - Memory 1GB

the same issue, so i think i do something wrong with the way i install the CWP
i have 2 questions?

1. Change the hostname> for example I use the domain cwp.mydomain.com, do i need to change anything in mydomain.com (for example the name server, dns setting) ?

2. Setup Server IP addresses
Define additional IP address, subnet address, and default gateway IP address for your server — your service provider can provide you with this information
if i'm using AWS / Alicloud? do i need configure this or i leave it just the way it is ?
coz i see some articles said i need NetworkManager-tui (nmtui) then there's no explanation what i've to do with it. so i just leave it all automatically.

need advice.
