Upload images error in multisite

Hi I had a site: https://2wsinforln.com/ that is a one page site, and I create a multisite network. I create https://ita.2wsinforln.com/ and https://eng.2wsinforln.com/ I create them by copying https://2wsinforln.com/ with “NS copier” plugin it worked flawlessly and image uploads works with no issue in all the 3 sites.
Then on the same exact server I had https://2winsolutions.com/ that is a lulti page site and I create multisites. https://ita.2winsolutions.com/ and https://eng.2winsolutions.com/ I try at first with NS copier but it didn’t work and then I roll back the database and I try to clone them with “MultiSite Clone Duplicator” plugin and it work flawlessly and it was a quick operations. However once I try to upload images I get no errors https://2winsolutions.com/ but I get an error in https://ita.2winsolutions.com/ and https://eng.2winsolutions.com/. the error is “An error occurred in the upload.Please try again later” I try to find where any setting for the upload folder is with no result… Any idea?
