Problems with Ledger Nano X and ociswap.com

[dazligth]

Hi Guys,

got problems singning transactions via Ledger Nano X by using Z3US Wallet via ociswap.com
Ordinary sending XRD from Wallet to another address works fine.

Wanted to swap 100 XRD into OCI for a test on Chrome Version 103.0.5060.134 (Offizieller Build) (64-Bit).
Connected my wallet which was fine.

I push "Confirm Swap" and a window opens for "approval".
At this point, the ledger seems unconnected, even it was connected before. (And yes - radix app is ready on ledger).

The I push recconect and connection is "back".

Then by pushing "Approve" it will fail.

"Failed to sign tx with Ledger, underlying error while streaming tx bytes: 'SEND APDU failed with underlying error: 'Ledger device: UNKNOWN_ERROR (0xc6e0)''

This is a known issue, and we are working with Ledger team to investigate the root of the problem,
So far we suspect it's the radix ledger app, and in the worst case scenario we will have to w8 for radix team to fix it, in which case I would not expect any resolution any time soon since the radix team is busy with babylon.

In the meantime, since the ledger transaction will work from the wallet directly (not trigger by dapp) we are working on the view of all pending action, which hopefully would allow you to approve it from there without above ledger error.

This issue was solved with https://github.com/z3us-dapps/z3us/releases/tag/v1.0.15%2Bext release.

Okay ... now I tested adding liquidity @ociswapp

XRD / EMOON Pair.
Oh no! Anerrorhas occured.
Failed to sign tx with Ledger, underlying error while streaming tx bytes: 'SEND APDU failed with underlying error: 'Ledger device: UNKNOWN_ERROR (0xd104)''

In this case my Ledger stops to operate. Had to unplug it, the had to reentry the pin, than it stucks again in PIN-Login-Screen ... but after some time it shuts off. When I start it again, PIN Login works now and it comes back to normal operation.

Hi guys, changing the PAIR to EMOON / XRD will make it work!
