Files cannot be uploaded

I have tried for several minutes to upload some files for some products that I have just launched and the files do not load, only the description and the presentation photos appear but the files are not uploaded, when I choose the files I want to upload the upload bar appears, apparently it reaches 100% but does not advance and the files are not uploaded, I have tried with other browsers but it seems to be a problem with the site.
Why is this happening?

Thank you for letting us know, I have asked out team to look into this issue.

Thanks for your quick response, I’m still trying but it doesn’t seem to be working, I hope the problem will be solved soon.

Apologies for the much later response @fkorpsvart, uploads are now functioning again. Thank you for your patience.

Hello friend, again it is impossible to upload the product files. What can be happening?
