Elasticsearch v7.5.2 (I'm using it) Changing Port from 9200 to 9300 See below images you will get understand why i am facing this issue for the past 3 days i want to give port number of 9300 instead of 9200 in elasticsearch.yml file. After changing the port number i restart the service of elasticsearch after that its get failed to start and when i give http.port on 9200 it work fine but not on 9300. what is transport.tcp.port: 9300, i added in elasticsearch.yml file its correct or wrong to please see all images in attached. please do help me urgently ![3](https://us1.discourse-cdn.com/elastic/original/3X/4/6/46c9a4856c94904e79f02fee48df463b7266c41a.png) ![4 log files](https://us1.discourse-cdn.com/elastic/original/3X/b/2/b21368da16f5f0cf1a73d2eb309f290351b2595b.png) ![2](https://us1.discourse-cdn.com/elastic/original/3X/6/9/694affd58b0de57aba36fa15273fefc37ef8aaf7.png) ![1](https://us1.discourse-cdn.com/elastic/original/3X/4/6/4651c9b4997e4b6b8c4dea6b6bd1e3e465814a49.png) ![5](https://us1.discourse-cdn.com/elastic/original/3X/c/0/c0462952edc72bda4cdb673d733755eec7ae3e91.png) ---

Port 9300 is the default port used by the transport layer, i.e. communication between elalsticsearch nodes if you have a multi-mode cluster. Since you set `http.port: 9300`, you need set `transport.port` to something else. Otherwise you'll get port conflict. `transport.tcp.port` is for old version of Elasticsearch. Since you have v7.5.2, it should not concern you. In one of your screenshot, there is an error message says "Received handshake message from unsupported version: [5.0.0] minimal compatible version is: [6.8.0]". You will need to make sure there is no other "old" elasticsearch instance running and trying to join the cluster. ---

Please don't post images of text as they are hard to read, may not display correctly for everyone, and are not searchable. Instead, paste the text and format it with `` icon or pairs of triple backticks (```), and check the preview window to make sure it's properly formatted before posting it. This makes it more likely that your question will receive a useful answer. It would be great if you could update your post to solve this. ---

Sounds like you changed the transport port to 9400. So you might have to change this ``` spring.data.elasticsearch.cluster-nodes=${ELASTICSEARCH_HOST}:9300 ``` to ``` spring.data.elasticsearch.cluster-nodes=${ELASTICSEARCH_HOST}:9400 ``` ---

Where did you change the port number. Logs are still saying `127.0.0.1:9300`. > [@MdRashid](#): > > and do u have any idea on below issue > > ```auto > Caused by: org.postgresql.util.PSQLException: ERROR > > ``` It's not related to elasticsearch. ---

Here is the elasticsearch.yml configuration file i have set this in network # ---------------------------------- Network ----------------------------------- # # Set the bind address to a specific IP (IPv4 or IPv6): # network.host: 127.0.0.1 # # Set a custom port for HTTP: # http.port: 9300 transport.port: 9400 # # For more information, consult the network module documentation. ---

Please first make sure elasticsearch by itself starts up fine and works normally. The simplest way to ensure it is to start elasticsearch and then just issue a few curl commands to make sure it respond properly. If above works, you can then be sure the problem is in your Spring application or network. A simple Tip is to make sure elasticsearch and your application are not running in separate docker containers because `localhost` means different things in containers. If you still keep getting errors from your Spring application, you might wanna take the question to Spring Data Elasticsearch since they are the experts on this particular topic.
