Error: Can't connect to the backend! Maybe its down.
Ubuntu Server 16.04
Provider is Scaleway.com
box size is C2L, 8cpu32ram

steps to reproduce  
https://github.com/moneroexamples/openmonero/blob/master/README.md
chrome browser - exampleapp.com/



result is that the app successfully creates a mnemonic key, however there is a notification on the splash page that says `Error: Can't connect to the backend! Maybe its down.`

pasting the mnemonic key in the box below it after being created gives the following error: `server error`.

a clue, the title bar branding says "testnet" despite all testnet options set to false as well as openmonero being run without the testnet option.
