First time deploying meteor app with meteor-up - meteor

Question

This is the first time i am deploying from Meteor-up and I followed the docs to deploy a dummy application first. I am deploying on a shared linux server. Everything is going great but i can't find my app on ROOT_URL. My domain is pointing to the server and that very domain is also my ROOT_URL. when I hit the domain link it goes to the index of file explorer on the server instead of my web app. I tried to find logs but logs command and --verbose flag returned no log and the command simply run as usual.
Mup version (``1.5.3`):
Mup config
{ "servers": {
"one": {
"host": "1.2.3.4",
"username": "totalti1",
"password": "password",
"opts": {
"port": 2083
}
} }, "proxy": {
"servers": {
"one": {}
},
"domains": "host.com,subdomain.host.com",
"shared": {
"httpPort": 80,
"httpsPort": 443
} }, "app": {
"name": "my-app",
"path": "../.",
"deployCheckWaitTime": 300,
"servers": {

},
"buildOptions": {

"MONGO_OPLOG_URL": "mongodb://localhost/local",
"VIRTUAL_HOST": "host.com,subdomain.host.com",
"HTTPS_METHOD": "noredirect",
"VIRTUAL_PORT": 3000,
"HTTP_FORWARDED_COUNT": 1
},
"docker": {
"image": "abernix/meteord:node-12-base",

"stopAppDuringPrepareBundle": true,
"imagePort": 3000,
"args": [

},
"enableUploadProgressBar": true,
"type": "meteor" }, "mongo": {
"version": "3.4.1",
"servers": {
"one": {}
},
"dbName": "DemoApp" } }
the port of my host is 2083 and I am not sure if that is causing a problem. I am not sure if the deployment was unsuccessful or the URL had a mistake. I was able to get some log after setting the debug Environmental variable. And here is it.
Output of command
$ DEBUG=mup* mup reconfig --verbose

I am looking for some instant help as i am stuck on this deployment for three days now. Thanks in Advance
EDIT
Is there a way to know that the deployment was successful or not. Also is there something wrong with my ROOT_URL? Root url contains the IP of server on which i have hosted the app. The domain also points to the IP. When I access by IP it says
Sorry!
IP changed or server misconfig or site may have moved to different ip. Contact your hosting provider.
When i access via domain it shows the empty directory the default domain is set to.
