Sorry, It was my bad, I found that two slashes (\\) was into key file. Apparently newer versions of ROS just ignore it....Unable to import 4096 RSA public key at 6.45.8...
/user ssh-keys import user=test public-key-file=pub-key.txt unable to load key file (wrong format?) !
+++It's an old and very clever rule for every software - never put in production new release before first bugfix subrelease, so in this case wait for 6.46.1 at least.
All the same!I also have the same problem session stops on the DHCP offered. The problem is version 6.38 and higher. Version 6.37.4 is ok.
