Olympus FL-600 flash on OMD E-M1 Mark II issue

Hoping someone might be able to help here.  When I place the FL-600 flash on my OMD E-M1 Mark II it will not fire.  The flash is in TTL mode and displays changes in focal length.  If I turn the camera RC mode on the flash will work that way.

If I remove the flash and place it on my Pen E-P5 for a picture it works with no issue and if I move it from there back onto the Mark II it will work perfectly on the Mark II until I turn the camera off then it goes back to not working when I turn it back on.  The shutter is not on silent.  The flash that comes with the Mark II works fine.  I don't even know if this is a flash issue or camera issue?

Electronic shutter

high speed sync activated?

some art-modes do. Not accept flash

somerimes my FL600 Gas contact--issues on both my EM 1 II and PenF, push it straight forward

flashmode?

serial shutter?

proMode?

Internal Flash Not activated in RC Mode?

I had a similar problem with the EM-1 mk. 2 and Olympus FL-50R flash as well as the mini-flash that came with the camera.

If you are using electronic shutter, the flash will not fire. If you change to the mechanical shutter it works fine.

Flash is pushed all the way on

Not sure what serial shutter means

when pressing the shutter is does not make a single "klick" it makes "klickklickklickklickklickklickklick...." and makes pictures as long as you pressed the shutter. In this mode flash is always off ... on every camera.

Try doing a setting reset on the em1 mkii. When quirky thing like this shows up a full reset does the trick.
