No new versions, also tried with “Command Pi” App 
Ok, let me know when you have two non working Vero’s
Yep, now i got two non working ones
Ok try the following:
sudo nano /etc/ssh/sshd_config
Put a # in front of the line that starts KexAlgorithms and also the one starting Ciphers
Ctrl-X and Y
Then
sudo systemctl restart sshd
And try again
The config file is empty on both devices ?
Sorry was missing the folder, correct see above
there is no sshd_config only ssh_config
hmm i can find it with Winscp
Don’t use winscp as you need root rights.
Use putty to ssh in and then run sudo nano /etc/ssh/sshd_config
same error :

Did you restart sshd?
Yes, there were a third line, it’s working now 
but what does this mean, is my system less secure now ?

Yes, it is less secure but unless you have your SSH open to the internet it is not a major issue.
But as mentioned at the beginning suggest to figure out why you have a device freezing.
Or are you saying Kodi is freezing. Then you could use Kore to just restart Kodi.
Thanks a lot, you have been really helpful
Is Kore an app ? seems like it’s android only - yes it’s kodi that are freezing, usually happens when a media file is not supported
thanks, will try that next time it freezes
