WordPress content image not properly importing

if I import a wordpress post, the post image is imported only as a super tiny image, a couple of pixels big.
You mentioned by email this might have to do with a switch from http to https that we did a couple of months ago - is this really the case? what’s the fix?
Thank you!

Well, did you put your website on https right now?

this seems to be fixed now, thank you!

you can close this case
