Make sure you copy the correct URL! Always look for a link labeled something along the lines of "permalink", "permanent link", "persistent link", "record URL", "durable link", "bookmark", "stable url", etc. Only copy the URL from the address bar if no other link is available. See screenshots below for instructions for each database.
