Hi @naarkhoo, thank you for reporting this issue. Could you try upgrading to version 1.0.32 of the extension?

Anthony_Carreon · September 21, 2025, 8:18pm

Upgrading to 1.0.32 for the ssh extension fixed my issue! I too was having this problem with the exact same error.

whistler · September 21, 2025, 8:21pm

Thank you! This also helped fix the issue for me
