Title says most of it. I've been at this for hours with almost no progress. There are two codes (37068 and 57063) that didn't work although they seem to fit the conditions given. Can someone please give a clue to put me on the right track? I feel like I'm going absolutely nowhere, but would still like to figure it out.

Update: The owners of the website have fixed itthe code. Apparently it was bugged and the visible number code that were hints weren't changing, although they were supposed to. This made the puzzle impossible since the answer was changing each time the page was refreshed or you attempted to crack the code.
Thanks y'all for helping before and after the fix!
