Stuck on build 14393: cannot update

I am on build 14393 and I am trying to update to 14905 or 14915, but when computer restarts after trying to update I get a message that windows is rolling back to previous version (my version 14393), without making the update. I tried through windows update, i tried also downloading the iso and update windows via iso and i tried updating via windows media creation tool. All efforts had the same result, which was rolling back to version 14393. Any thoughts? Must be a minimum hard drive space available? Cause i have 55 to 60 GB free disk space.

Is your version 14393 an Insider version?? If not you can not update to 14905 or 14915.These versions are exclusively, for now at least, reserved for the Insider. The standard version (official general release) is 14393.105 .
