i'm reindexing docs from one index to another and usually i got this exception which i dont know what cause it, in my local pc i didnt have it but in az pipeline it happens frequently . this is the code i'm using to do the reindex :

var result = await client.ReindexOnServerAsync(r =>
            {
                return r.Source(s => s.Index(startIndex))
                    .Destination(d => d.Index(finalIndexName))
                    .Script(s=>s.Source(scriptContent.Source).Lang(scriptContent.Lang).Params(scriptContent.Params))
                    .WaitForCompletion();
            });

This suggests that the client connection to ES is not working. Do other functionalities other than reindex work? e.g. if you index or query data via the client? How are you running ES?
