RPC

Dear AION team,

I tried to set up the solo_pool, aion kernel and miner by following the documentation. Though I think something is wrong on the solo_pool as I keep having errors in the logs.

It seems the pool does not connect well to the aion kernel (problem 1), and then there is an error on the pool when the miner connects (problem 2).

What I did:

1. Start the solo_pool
2. Start the aion kernel
3. Start the miner

The solo_pool logs look like:

The aion kernel logs look good.

The miner logs:

After I turn on the miner, I get this messages on the solo_pool:

Could you please help me solve the issue ?

Thank you in advance,

Could you try replacing the api-enabled setting in your aion kernel with the following:

<apis-enabled>web3,eth,personal,stratum</apis-enabled>

The errors with the miner are normal when the pool as not been able to connect to the kernel.
