@ripStarfola like haitch said, all looks ok ... you configured faucet to run at port 5454, so you need to access it under that port ... within the server you should be able to access faucet e.g. at 127.0.0.1:5454 ... not sure how you configured your domain.
burstcoin.faucet.walletServer=https://wallet4.burstnation.com:81255 <- guess it should be 8125
btw. i suggest not use online wallet faucet will commit the secretPhrase
