Hi @jeromelinjianlong, any logs, OS, context? We need more data.

I am facing the same issue. It happens after I installed the miner and at running ./target/release/grin-miner. I use Ubuntu 19.10.

Here is an excerpt of the grin-miner.log:

@ptrk01 Looks like a different issue. Are you launching the miner from the directory with the config file? (i.e. grin-miner.toml)

[ptrk01]

@quentinlesceller Yes, I do.

I followed these steps https://pastebin.com/raw/f3AFztWj (used a different mining pool, not the one in the file)
