Can't sign in with Ledger Nano S

Doesn’t recognise ledger.
Note I use for signing via gaiacli without problems.
running full node.

Could you describe your setup a little more? Is the Ledger plugged in directly to your node or remote via cli? What exactly are you doing and at which step do you strugge?

Note: This issue has been posted in “Wallets & UIs” so this probably targets signing in Cosmos Wallet.

Which OS / browser are you on?

MacOS Mojave 10.14.2 Beta (18C38b) with Safari, Version 12.0.2 (14606.3.4)
Just discovered chrome works !!!
