Cntools error during hardware wallet signing

Staking & Delegation Operate a Stake Pool
#1

Hi all,

I’m trying to setup my Trezor model T, to use as pledge in my pool.

I’m using cntools for the whole process, in hybrid mode.

I run into a problem when cntools is trying to witness the pool update transaction with my Trezor.

"INFO: follow directions on hardware device to witness the transaction
Error: Unexpected message

ERROR: during hardware wallet signing !!

press any key to proceed …"

All the software is up to date, for cntools, trezor bridge and cardano-hw-cli, and I had no issue importing the HW wallet beforehand. Only this step doesn’t work.

I’ve been scratching my head for a while now, and can’t find what I’m missing… Thanks !

Can be related?

#3

I had never heard of Trezor Connect, so I looked it up.
It seems to be another utility, independent from Trezor Bridge, which I am using.

So not related.

#4

Then it’s looks like a connectivity issue, try to connect the trezor before cntools … or try to run again the prereqs.sh -w

#5

I did run prereqs.sh -w just before.

I also connect/unlock my trezor before running cntools. And my trezor does “react”, something happens but it stops halfway through.

Might be a compatibility problem between the tools and the new 2.4.2 firmware.

I ran into the same problem, although I was able to sign everything before. Remembered I just upgraded the Trezor’s firmware to 2.4.2, so I downgraded it back to 2.4.1 and got it working again!

That’s it, downgrading to 2.4.1 worked for me as well !

Thank you so much !

I had the exact same problem. I was able to fix it without downgrading my trezor’s firmware.

The solution was found in downloading the most recent beta/pre-release of the cardano-hw-cli.
version. 1.8.0-rc0. Replaced existing binary in $HOME/bin/
