I've been working with MLT handler (Solr 8.1.1) by calling it the same way you did, http://[SOLR URL]/mlt. But the response is very unreliable with 90% of the same queries resulting in Java null pointer exception, and only 10% returning expected response. I do not know what is the cause of this.
I overcame this problem by using knnSearch via Stream handler ( https://lucene.apache.org/solr/guide/8_1/stream-source-reference.html#knnsearch). It is just a wrapper on MLT, and it works brilliantly. It is worth checking it out if you are running Solr in cloud mode. If you pass the fl="score"&sort="score desc" to knnSearch, you will be able to get the results sorted by matching scores.
