Blog not being crawled by Google

Hello everyone!

I know this question has been brought up several times, but I did not get closer to a solution by reading through older posts so far, so help would be appreciated.

I have set up my blog some time ago but it doesn’t appear in Google Search even when I’m searching for its direct URL site:blog.carmafluxus.com.
I have submitted the site using Google Webmaster Tools but there still are 0 crawls and both Google Search and Webmaster Tools blame the robots.txt file, which can only exist in a virtual form, as it is not located anywhere on the server.

It’s apparent content is the following (taken from https://blog.carmafluxus.com/robots.txt)

User-agent: *
Disallow: /wp-admin/
Disallow: /wp-includes/

I am not an expert on this but the file as such seems to be alright. Is there an issue I am not aware of? What should I do next?
