Newer log home in Alaska and going some insulation. Had thermal images done and major air leaks all along the interior ceiling, so I sprayed foam along seam, inside of thermal barrier. -20 degs. for 2 weeks, warmed up over freezing, now have water dripping down inside walls, leaking through vapor barrier? What did I do wrong and what do I need to do to fix It please, I love this house, but i’m losing.

First you should never use the spray can foam on a log home. I would dig it out and have a roofer look at it for ventilation issues.
