Connecting to custom substrate node

[6636345e]

Hello.

I have a seperate customized substrate node in a server and when I try to connect the endpoints using Polkscan explorer, it does not want to connect to the exposed endpoints. *Seen screenshots below:

• I commented the line - SUBSTRATE_RPC_URL=ws://substrate-node:9944 since I have customized node running on the server.

• Changed to - SUBSTRATE_RPC_URL=ws://10.11.101.23:9944

  

• After the explorer run, on the browser it does not connect to the explosed endpoints from the node.

• Instead, it shows the display in the screenshot below.

  

• Any advice on this?

The first endpoint labeled "Local node URL" in the connection dialogue is the URL to the Substrate node, so that should also be "ws://10.11.101.23:9944" in your case. You can change this in the UI config file: https://github.com/polkascan/explorer/blob/main/explorer-ui-config.json

• Thanks for the response!
• But I have changed 'Local node URL' to 'ws://10.11.101.23:9944' but it still display "connecting".

Also when I run the Substrate node locally, it does connect. But not on the server which is the goa, running the node and explorer on the server.

Have you run the Substrate node with --ws-external --rpc-cors=all to allow external connections?

Yes, substrate node with ./target/release/node-template --ws-external --rpc-cors=all. I am not sure if it's because I am running it as Docker docker-compose up --build and I noticed that the DOCKER image is pulled from arjanz/substrate-node-template:latest but I want it to connect to the local substrate node not use the node from the docker image.

• Getting same results as screenshots above

I still see ws://127.0.0.1:9944 in stead of ws://10.11.101.23:9944 in your screenshot, I think because it's stored in your browser's local storage. What if you manually replace it there with ws://10.11.101.23:9944?

Yes this was actually temporary hosted from my personal Docker hub account, thanks for noticing, I'll replace it with the Polkascan one as it should.

Oh yes thank you, it was stored in my browser's local storage, thank you now it connects

Glad I helped while asking help myself, thanks for assistance.

• I cleared my browser and changed "Local node URL" to my substrate node endpoints
