Looks like protection circuit tripped. I'd try with a higher voltage, and don't be afraid to put some current through it but keep it short. Say 4V, 1A current limit. Or use another Li-ion to 'jump start' this one. Only a second or so should do.
If that doesn't work: regular charging voltage (4.2V), but with a high-value series resistor (~1K ohm) to limit charging current to a few mA. Leave that for a couple of hours.
If that also doesn't work: remove protection circuit & re-rewrap the cell.
In any case: as soon as battery shows any signs of life, remove external power & check resting voltage. If the cell sat in storage at a low voltage (<2.5V or so) for too long, it could be unsafe to put back into service, have increased self-discharge, or lost a good deal of its capacity. Charge at a low current (0.01C or so) until cell is back into >3V range.
Oh and just to be sure: before doing anything, check multimeter against other voltage source(s). When you're satisfied multimeter works correct, don't mess with its range settings before measuring your 26650 cell.
