With default settings.json file[1], you should able to do it by entering localhost:3001 on your browser.

Depends where you have installed the files and running the Block Explorer.
If you have set it up on your PC or on an raspberry pi at home you can get there as mentioned from ETFbitcoin .
If you have installed it on a VPS and Server Provider and the setup is done right you just have to insert the IP from your VPS in your browser or the domain if you have one.

i have the block explore installed on digital ocean at xxx.xxx.xxx.xxx

our wallet is running on digital ocean as well at xxx.xxx.xxx.xxx

our default rpc port is 7143

i have the block explore installed on digital ocean at [IPv4]

our wallet is running on digital ocean as well at [IPv4]

our default rpc port is 7143

I doubt it's good idea to share your public IP like that, but what you should enter is IPv4 of VPS which contain block explorer. The port i'm talking about is port under comment "// port to listen for requests on." which should have 3001 as default value, not RPC Port.

i changed it back to 3001 but still not working


should the "instance" address https://github.com/iquidus/explorer/blob/master/settings.json.template#L10

and the "database" address be the same? https://github.com/iquidus/explorer/blob/master/settings.json.template#L37-L44

im assuming the instance address is the ip of the server where i have the block explorer installed right?

also

how is this port number derived? https://github.com/iquidus/explorer/blob/master/settings.json.template#L43

That's weird, you typed [IPv4]:3001 on your browser right? Does npm show any error or warning message when you start the server?

no error messages. its not immediately spitting out any feedback though either as it did on default. that has me concerned.

maybe im not running all the necessary flags on the wallet?

Looks like there is not all started or the setup was wrong done.
If all would be right installed and started you should be at least see the Iquidus Explorer Page when you typing the IP from your VPS into the Browser.
Maybe this Video here will be helping you to set it up right and get it working https://www.youtube.com/watch?v=laeV2slJgc8

Code:

--Block explorer pastes

sudo apt-get update
sudo apt install nodejs-legacy
sudo apt-get install npm
sudo apt-get install

sudo apt-key adv --keyserver hkp://keyserver.ubuntu.com:80 --recv EA312927
echo "deb http://repo.mongodb.org/apt/ubuntu xenial/mongodb-org/3.2 multiverse" | sudo tee /etc/apt/sources.list.d/mongodb-org-3.2.list

sudo apt-get update
sudo apt-get install -y mongodb-org
sudo systemctl start mongod

Start mongodb cli: 
mongo
use explorerdb
db.createUser( { user: "iquidus", pwd: "3xp!0reR", roles: [ "readWrite" ] } )
exit

git clone https://github.com/iquidus/explorer explorer
cd explorer && npm install --production
cp ./settings.json.template ./settings.json

To use forever to start (run in directory of explorer):
forever start -c "npm start" ./

crontab information:
*/1 * * * * cd explorer && /usr/bin/nodejs scripts/sync.js index update > /dev/null 2>&1
*/5 * * * * cd explorer && /usr/bin/nodejs scripts/peers.js > /dev/null 2>&1
