Cannot connect to GRPC port when node is running

fussybeaver opened this issue · 4 comments

I have a node running (fussybeaver on the dashboard). Logs of the first 100 lines: https://gist.github.com/fussybeaver/68a32d24479d753834a58ba2c9275457

However, I cannot use concordium-client properly:

concordium-client consensus status
Error: I/O error: Cannot establish connection to GRPC endpoint.

netstat shows port 10000 is not open (only port 8888). I'm running Arch Linux kernel 5.10.17-1-lts.

The concordium-client will by default try to connect to localhost on port 10000. Localhost is almost always 127.0.0.1, but it could be configured differently on your system. Try changing IP and/or port by using --grpc-ip and --grpc-port flags.

@fussybeaver, just saw that you discussed the issue already to some extend in discord. So I guess setting the flags as mentioned in my previous post doesn't help?

Ah yes, setting the flags does indeed work:

concordium-client --grpc-ip 127.0.0.1 --grpc-port 10000 consensus status
