Both ./grin-wallet address and ./grin-wallet account work normally.

Version info:

grin-wallet: v5.1.0
OS: Ubuntu 20.04.4 LTS (GNU/Linux 5.4.0-120-generic x86_64)

About tor:

I have no tor installation. By running ./grin-wallet listen, I get

I see this address “pk7q3gkqczkzfgscjzpcvvexdmk34wqukmkeq4s7xjmpk53bixfopoad”. However, my address displayed by grin-wallet address is different.

$ grin-wallet address
grin102lsmx<omit on purpose>

Is this OK?

Is your node running on the same machine? If yes then restart the node and try again

3

Yes, on the same machine. I have restarted the node and seen the Running status for several times. I constantly see this error message.

i’m not on a pc where i have node/wallet so i can’t test anything, but the problem in your case is that your wallet can’t connect to your node’s foreign api. Node’s foreign api should be available when you start the node. It’s normal that grin-wallet address works, because that call doesn’t need a node (and that’s actually your address, i would ignore the TOR address - that’s probably ed25519 pubkey or smth). You don’t need to run grin-wallet listen for the wallet to communicate to the node, that’s only for tor sync communication. I would run netstat -tunlp and check if you have 0.0.0.0:3413 or 127.0.0.1:3413 there.

I have to run grin-wallet listen because I want to do solo mining locally to bypass the internal network blocking of all available mining pools.

Here is my netstat output

$ netstat -tunlp

I think you need to install TOR. Maybe someone else can confirm

7

But from the output, it seems it is OK without tor?

8

i think http is deprecated but i’m not 100% sure. But the node connectivity issue is not related to tor

9

Wow, so the output message of grin-wallet is not updated accordingly? Then the quality of the overall Grin project is questionable…

Patches are always welcome :slight_smile:

Try ufw allow 3413

13

Or upgrade the grin version to 5.2.0-alpha.2. I had also issues with version 5.1.2 to solo mine. Now its running super stable.
