Photos from Lightroom

To clarify, are you getting an immediate error message when you upload the file warning you the quality is too low? If so, this is automatic and is not so much a subjective process as the moderation process that happens after you submit the file and it's reviewed by humans. If you are getting that automatic error, there is something wrong with your file.

If however, you are uploading the file, then submitting it for review and receiving an "artificats" error message that is usually an indication of excessive noise, however it can be other artifacts as well. Based on the low rez file you uploaded here (that's not the exact file you're trying to upload right?) I'm seeing what appears to be sensor dust spots which can result in artifacts rejection. If you don't already own a rocket blower, now is the time to buy one!

I found out if i upload directly from Lightroom to Adobe stock it makes a world of difference.

I can take the exact photo which might have been compressed to much and calls for it to be low quality, into the the stock with no problems with the direct publish from lightroom

So you can upload directly to Adobe Stock through Lightroom. However, depending on your settings depends on the amount of compression and noise. You need to look at your  Export settings. You should save your images at 100% for Adobe Stock images at full resolution - hence it being easier to upload through Lightroom. 

It is hard to tell if there is noise or compression from your image at this resolution. Always view your images at 100% before submission.

Hello,

Firstly to give any concrete advice can you upload an example here of your rejected photo/s?

Secondly, you can upload to Adobe Stock directly through Lightroom in the Library Module under Publish Services. Are you using Lightroom Classic or Lightroom? There are two different versions now, so which version are you using?
