I have set up a server computer on my local network with a cardano node and cardano-submit-api.
I can use the cardano-submit-api on the machine locally (http://localhost:8090/api/submit/tx with ) Nami, however Im unable to use the it from another machine on the network i.e.
http://[serverip]:8090/api/submit/tx. transaction fail and “cardano-submit-api” on server doesnt register any attempt.
Anyone seen this issue and might know what to do?
Note: im not a server genius but I am able to remote ssh to the server machine
Looks like it only binds to the localhost loopback interface by default.
I don’t have one here to test and the documentation is … not very comprehensive: cardano-node/cardano-submit-api at master · input-output-hk/cardano-node · GitHub
If they have done it consistently with
cardano-node, starting it with
--host-addr <server-ip> as an additional option maybe does the trick.
You can also try
--host-addr 0.0.0.0, which for most servers in the Unix world means “bind on all interfaces”. (Otherwise, localhost will not work anymore, after you have bound to the other address.)
Thanks !! This helped me a lot!
I put in
--host-addr 0.0.0.0 , when I installed, but tried but no idéa why I tested it!
(My interpretation is that) this applied to cardano-tx-submit too, I changed to
--listen-address <server-ip> when running cardano-submit-api and "Running server on " instead of “Running server on 127.0.0.1:8090”
did u opened the port in fw?
It was not needed for my pcs on my local network. But I did open the port so I can use it off-network. Not 100% sure how saifu that is though
how have you defined the rules on the modem site? Because I have currently some problem to send the transaction from outside my network
I actually only just opened 8090 for that machine (you can try dmz the machine just to see if it is a port forwarding issue). However, I’m planning to redesign my server/network and will do some testing with using ssh-forward via tunnel, and make it “localhost”-only again.
