Trouble opening cloud files

Cannot open some files through the creative cloud. I've attached a screenshot of the error.
I had this issue a few weeks ago but it seems it has returned.
I am the only user and owner of these files, I have tried illustrator beta, the regular version, deleting and redownloading the apps, but no luck, the only way I can open these files is if Idownload them locally which in itself takes about an hour for a relatively small file on a strong internet speed, it is not realistic to do so.
This problem desperately needs to be addressed.
