I set up discourse via the documents and I installed discourse on DigitalOcean VPS. I changed all the nameservers to DigitalOcean and added my web domain URL to the project in DigitalOcean.
For some reason it stills shows Godaddy Lander page??
How do I fix this issue and start setting up Discourse?
I had it on Godaddy default nameservers and waited 48 hours, the webpage still displayed the Godaddy Lander page after installing discourse on DigitalOcean VPS (followed all steps in installation document..)
It sounds like you have a stray DNS record somewhere. When I use https://dnschecker.org/ to have a look at http://bidsturf.com/ it does seem that it’s pointing at two places.
You may need to contact godaddy and see if they can remove the redirect if you no longer have access.
From the screenshot you edited out, it looks like you are trying to access the file in your own Windows computer. To be sure, are you running Discourse in development or production?
