Scenario:
- I am running the irs-demo application on Linux instance
- NodeExplorer is installed on Windows instance
I try to connect to BankA node of irs-demo, to view the nodes vault and transactions with the help of NodeExplorer, using following command:
java -jar corda-tools-explorer-3.2-corda.jar
Following are the credentials of PartyA that I have used to login to NodeExplorer
Corda Node: <IP_address_of_Linux_instance> Port: <RPC_port_number> Username: <RPC_user> Password: <RPC_password>
Observations:
- When no transactions are performed by PartyA, I can successfully login to the NodeExplorer and connect to PartyA, using about credentials
When I make few transactions for PartyA using Web Browser, and then try to login to the NodeExplorer using same credentials, following exception is thrown:

Note:
I got the same exception, if I run the irs-demo application and NodeExplorer on single windows instance
