DKG Example failing "dial backoff"

[mvanmeerbeck]

Is this a BUG REPORT or FEATURE REQUEST?:
BUG REPORT (but probably just miss configuration)

What happened:
I can't get the dkg example to work, except few "Received request" and "Sent message ", the nodes keeps failing to connect to others nodes with the error
"dial backoff"

What you expected to happen:
I didn't do much except following the DKG demo, launched the 3 commands locally. No file is created in ./example/dkg
Here the logs

How to reproduce it (as minimally and precisely as possible):
make tss-example

and on the same machine, in 3 terminals:
./example dkg --config dkg/id-10001-input.yaml

./example dkg --config dkg/id-10002-input.yaml

./example dkg --config dkg/id-10003-input.yaml

Anything else we need to know?:
Thanks for this work & your help!

Hi mvanmeerbeck,

We will check it and fix it. Thanks for your information.

Hi,
I also tried all the releases 1.0.0, 1.0.1 and 1.0.2, same problem.
FYI, i'm on ubuntu 18, go1.20.1

[cychuang0924]

Hi, I guess that the threshold t = 2 in your situation. You can set threshold t=3, then 1, 0, 0 and 1,0, 1 should be passed. If the above guess is wrong, please let me know. Thanks a lot. Sincerely, Chih Yun Maxime Vanmeerbeck ***@***.***> 於 2023年3月8日 週三 下午6:58寫道：

I didn't change any configuration so t=3 already

port: 10001

threshold: 3

If i use only 2 parties, it works

port: 10001

Hi mvanmeerbeck,
The codes of example should be updated, so we will fix it as soon as possible.
Apologize for any inconvenience.

[mvanmeerbeck]

Thank you,
FYI, the example works fine with go 1.18
