Backendless Standalone - Rest Console Not available

I have a Backendless Standalone server installed on CentOS v6.7. I don’t have Rest Console functionality. When I click on the Rest Console Tab, nothing happens and the Rest Console tab never is displayed.

Are there any errors in browser’s console? Any 404’s in the network tab of the browser’s developer tools?

Strangely, I had to login into the standalone server from the browser and this time the REST console tab after click on it, responded with the REST console. I checked the network tab and there were no errors. I’ll report back if I see this problem again.
