Publishing to sharepoint error 403, 409

Hi, when publishing to Sharepoint Online I always get the errors 403 or 409. This is new, I didn't change anything. The sharepoint folder I like to publish to, is also existing and there are already other processes published. Is there maybe a problem when the models are saved in the cloud and not in the group? I can see the different libraries on the sharepoint site during the publishing process, so access is ok. Can anyone help? Thanks
