Ethminer: terminate called after throwing an instance of 'boost::exception_detail::clone_impl<dev::BadHexCharacter>'

[andreikorchagin]

Hi all,

I'm using the latest version of ethminer built from source on Ubuntu 16.04. Every attempt to start mining is met with the same exact error:

18:09:12|stratum  Connected to stratum server <server that I am using>
18:09:12|stratum  Starting farm
18:09:12|stratum  Subscribed to stratum server
18:09:12|stratum  Received new job #14c7
terminate called after throwing an instance of 'boost::exception_detail::clone_impl<dev::BadHexCharacter>'
  what():  BadHexCharacter
Aborted (core dumped)

I'm only using the flags -G , -S, and -O for GPU usage, Stratum server, and login credentials respectively.

I've looked online to no avail. How can I solve this, and is this an issue on my end/the server's or a bug?

Could you post your launch file?

I got a similar error. Here's the BT

I got this response from suprnova.cc

Same error as OP..
I fixed it by using the -SP 2 (in my case) to set stratum protocol.

I think the solution has been found.
