Hi, using Datomic Cloud, what might be causing these errors?

{
    "CognitectAnomaliesCategory": "CognitectAnomaliesForbidden",
    "CognitectAnomaliesMessage": "Db signature mismatch",
    "Msg": "Cluster auth failure",
    "Type": "Event",
    "Tid": 266,
    "Timestamp": 1788103716221
}

If this could have been caused by me deleting a database and reusing the name soon after, then I'm not worried as it won't happen in producton...

Yes that is most likely. Once a DB is deleted it takes some time before it is fully cleaned up. If you attempted to use the same name again you could get an auth error.
