Subject: [DNA] x chromosome puzzle

Hoping someone here can explain this one for me re a match at 23andme:

woman has a 30cM share on the x chromosome with my 2 sons but nothing
shared with either myself or my mother.

Also, she is predicted as 4th cousin to my sons.

She is adopted so we can't just figure this out via paper trails.

Is our connection definitely/only/necessarily [?] through my father's side?

And why doesn't she share with me? Is that due to recombination
effect or something else?

Help?!

Thanks
AR
