Unsupported HMAC algorithms - could not settle on hmac_client algorithm

I recently installed a Cisco Switch with latest firmware It has the following SSH configuration

#sh ip ssh
SSH Enabled - version 2.0
Authentication methods:publickey,keyboard-interactive,password

Oxidized (0.28.1) failed with the following error

I think that such HMAC algorithms are not supported. Any workaround?

Thanks

Did you try to do as explain in this article: https://github.com/ytti/oxidized/blob/master/docs/Configuration.md (SSH enabling legacy algorithms)
