All valid answers so far, and as you can see the reasons may be multiple.
I'd first want the walls prepped, not strictly "cleaned" as that won't have much effect on adhesion of proper mortars. Certainly the proper substrate has a lot to do with how well the tile and mortar adhere. Clean and dry is OK though.
Tile size also is involved and for walls many @ 1/2/4/ or 6 inch, are backed with a mesh allowing not only that they remain in alignment, but also to create and easier install. That said however, I tiled my entire bathroom, walls to ceiling in 16 x 16 Terracotta. I install wall tile by setting the first course (bottom to top) letting it set, then work my way up.
Mortars are the issue it seems, in your case, and they vary as well. I've used poly bled thin set often, as well as mastic. I use a 1/4 inch tooth, flat edge "knife". The mixing is also part of the entire "mix" in that you should work in small areas at a time, don't over water the mix, (I use Peanut Butter or mashed Potato consistency) and that comes with some practice as well. Too dry also is bad, as the mortars/Mastic's have bonding agents in them, just as regular concrete, and those agents are effected by the amount of water added.
I suppose you could just use a tube type commercial grade adhesive, such as liquid nails, but I wouldn't.

A couple of reasons. Wall not straight.Not correct tile adhesive.Tiles too heavy.Thats more than two reasons.One of the best ways to lay tiles on wall that doesn't easily take tiles; is to nail up harboard sheets to wall first. Then use correct tile adhesive and glue to wood. You have a straight flat surface to work with. Then you can finish of with capping tiles at top, or whatever you like. Secret is to make sure tile is for walls.They are usually lighter than floor tiles. Good Luck!

There could be residue on the wall. Try some rubbing alcohol on the wall , wipe dry and then try tiling. Or it may be too cool, crank up the heat some. Good luck.

I bought self stick floor tiles from Home Depot for my walls. The worker suggested I also buy Bond Enhancer Self-Stick Tie Primer to assure the tiles will stick. They wont stick!!! I've taken down all of the tiles and scrubbed, then reapplied this enhancer 2 times already!! Why wont it stick?
