Hi all,
the pools start but after a while shows a lot of errors, the miner receives jobs but reports an error (empty jobs?) any hint to solve this issue?
BTW: also reports a network difficulty of zero ...

This version of the pool software (solo) is no longer compatible with the latest (mandatory) OAN kernel version. If you wish to run your own pool you will need to use the aion_pool2 implementation.
