Connecting Metamask to private blockchain in Azure

I'm trying to connect to rpc in Metamask. Metamask keeps idling in the trying to connect unknown private network. Geth is running in a Linux Azure network. Its public IP is AzureIP
Im sshing into the server, then I run the following command:

geth --identity “TestNode” --rpc --rpcport "8080" --rpccorsdomain "*" --datadir testprivareDir --port "30303" --nodiscover --rpcapi "db,eth,net,web3" --networkid 1999 console

I get the following output among other things:

HTTP endpoint opened: http://127.0.0.1:8080

I then run miner.start()

I try to connect to this private network in Metamask by going to custom RPC and putting the address http://AzureIP:8080

And it just idles there. In azure I have the following network inbound port rules enter image description here

From my own laptop (not sshed into the server) I then run the command:

ping http://*AzureIP*:8080

And I get Request timeout for icmp_seq ...

How can I fix this or any advice to connect to the private network?

Solution

  • 127.0.0.1 is a loop address, the service only works inside VM.

    On your scenario, you need listen the service on 0.0.0.0 on VM's private IP. You could add --rpcaddr "10.0.0.4".

    geth --identity “TestNode” --rpc --rpcport "8080" --rpcaddr "10.0.0.4" --rpccorsdomain "*" --datadir testprivareDir --port "30303" --nodiscover --rpcapi "db,eth,net,web3" --networkid 1999 console
