What's Wrong?
After updating Claude Desktop to v1.2581.0.0 on Windows (MSIX), all SSH remote connections fail with "All configured authentication methods failed". This affects all existing SSH configs that worked perfectly before the update. No changes were made to server configuration or ssh_configs.json.
What Should Happen?
SSH remote connections should work as they did before the update. Password authentication to the remote server should succeed.

same here, rolled back to 104 from 105 after losing a lot of work , 106 and 107 continues to have that issue where I cant login or paste the key, im not able to disable fast mode either
The same from Mac OS. It is a mess
I had same issue, been going back and forth with claude for 3/4 hrs and this finally worked:
"Step 1: Generate a fresh, unencrypted RSA key on Windows
Step 2: Copy the public key to your server
Step 3: Test in PowerShell first (if it doesn't ask for paraphrase)
One known issue to be aware of
There's an open bug where Claude Code Desktop ignores your ~/.ssh/known_hosts for new connections and shows a "Host denied (verification failed)" error. If that happens, run this in PowerShell first:
powershellssh-keyscan >> C:\Users\YOUR_USERNAME\sshpath\known_hosts"

I hope it's fix quickly.
I solved it, I really thanks to you for your efforts
You're better than Claude !!!
