K, tried every possible solution and no go!
EDIT from here:
Things are back to normal since OVH dns wasn’t changed but Cloudflare only have been! Therefore, when played with OVH and made them similar with CF. Site 
showed up!
I have changed this and replied to my own topic to be a good lesson for those who might have this issue which I became pro in solving it to new comers…!
Next stop will be how to convert a wordpress site into discourse which I had in the past few months 
Hopefully, there are some good tutorials and help from those whom had this before me!
