Login with SSH-Keys

I make that work on my smartphone and one laptop. I login with ssh keys without password and check my keys are on DietPi. Then I want to add bookmark in Nautilus and login to my DietPi. I success as ssh via Nautilus but I have to paste user and password. Then I try second time and now my local services are down. I cannot login with ssh. My local IP don’t work. I cannot login nextcloud, Emby and other. That apps works OK on proxy external address. What could happen?

Edit. OK it works now. That was some long freeze on local address :grimacing:
Regards.

I don’t know what Nautilus is

In Linux with gnome DE, default File Manager.
