Hi Erez ta,

Have you removed all existing peer nodes from config.xml if you are trying to run your own local networks ?

Are you trying the released version of AION binary or building from source ?

Also it might be due to the mismatch of genesis file with the config file as mentioned in the following issue ?

As mentioned in the above issue, try to verify your config and genesis file according to this link
