Hi there,
In openssh version 8.3, they disabled SHA1 signed keys due to security issues. On 8.4 it was taken out.
Unable to negotiate with 192.168.xxx.xxx port 22: no matching key exchange method found. Their offer: diffie-hellman-group1-sha1,diffie-hellman-group14-sha1
Netonix firmware needs a newer self signed key. This has also semi broken my Netonix manager as it can't connect to new devices.
