You may have pulled it back to tight.

release the tension a little & see if it helps

Is the rear cog in line with the chainring? You can have quite a bit of slop in the chain, and it won't fall off providing it's straight.

What is your set up? Singlespeed specific chainring? Tensioning method? Axle fastening method?

There will be a tight spot and a slack spot in the chain with a singlespeed due to the tolerances in the chainring and sprocket (they're not always perfectly circular)

You want to get it tight(ish) in the tight spot of the chain, if you get it tight in the slack spot it'll be too tight in the tight spot

e thirteen guide ring
tensioning method is by pulling wheel back and tightening dropout bolts
