when you give a url to qdrantclient, the port is getting appended to the end of the url, this is wrong.
if you give QdrantClient({url: "https://qdrant.mydomain.com" })
the error received contains path: "https://qdrant.mydomain.com:6333/collections/my_collection" this is not a valid url and will generate the error.
if the url parameter is passed, no port should be appended to it.
