This is related to `22.x` version. It seems that my `devcoind` process crashes when somebody tries to connect to the node (perhaps there is another reason, I am not sure). Here is the thrown error: ``` ./primitives/block.h:40: void CBlockHeader::Serialize(Stream&) const [with Stream = CVectorWriter]: Assertion `auxpow != nullptr' failed. Aborted (core dumped) ``` Here is my config file: ``` rpcuser=user1 rpcpassword=Nzkfa1oZ5_JKMMJ-VZkXJM56dmomSEB3JqAFByFWUFU= rpcport=8999 server=1 ```
