Etheminer 0.19.0-alpha.0 API not responding

[RayLucchesi]

I am using —api-bind 127.0.0.1:3333 for my ethminer inside a docker container, and although I can use netcat to access that port, ethminer seems to be resetting the link before I see any response.

I open two terminals in one I use netcat and in the other tcpdump. I issue:

echo '{"id":0,"jsonrpc":"2.0","method":"miner_ping"}' | netcat 127.0.0.1 3333

In the tcpdump I see:

tcpdump: listening on lo, link-type EN10MB (Ethernet), capture size 262144 bytes

One can see the 3-way handshake that opens the port. The transfer of the data across the port and the ack from the ethminer receiving the data. But a) there’s no json response and b) the link is reset by ethminer. I’ve tried other commands. I didn’t assign a API password

Ubuntu 20.04
Ethminer v0.19.0-alpha.0

If there’s more info you need please let me know.

Seems like #1938, it was fixed a year ago but we haven't had a release since then, for windows you can download builds on the AppVeyor link on the main page, I believe for linux you would have to build it yourself. If you need new rtx support you could try #2133
