Do not board message at the airport check in

I have always experienced a do-not-board message when flying to Dubai from Kenya since last year January 2016. Since then I have traveled more than five times to Dubai with a visit visa but every time I check in at the airport with my passport the message comes, "do not board, contact UAE government".

Normally airline staff give me a manual written boarding pass as nobody seems to understand why and how I can have a new valid visa and a return air ticket and my boarding pass can't print.

I have visited all immigration offices in Dubai but no one seems to help or know where the problem comes from. I have never been convicted of any crime of any sort and I don't understand why this always happens to me.

Now I may not be able to travel as the airlines do not issue manual written boarding passes even though I have a new visa issued few days ago and a return ticket.

UPDATE

I have contacted the airline where they have sent me to the UAE immigration and I have done all they ask me to do but none of the two parties accepts the responsibility. Somehow I am wondering why the UAE government is directing the airline to contact them while I try to board the plane and my boarding pass can't print where I have all the correct and valid documents.

When the airline write to the UAE government on email there is no response for days and even weeks leaving me stranded and guessing what's going on. I have verified my visa passport and return ticket with the airline & the UAE immigration but still no help has come forth. I am really looking for any kind of help as this can be traumatizing. Thanx people of good will as I have not received any kind of help from my answer I dint know exactly I need to edit here while replying your messages.
