Problem when SSH into a firewall

L2 Linker

I can SSH from firewall to firewall, but when i try to SSH from a C brand router to the paloalto firewall I receive this error message:



*Sep 27 21:16:32.190: %SSH-3-NO_MATCH: No matching cipher found: client aes128-cbc server chacha20-poly1305@openss,aes128-ctr,aes192-ctr,aes256-ctr,,



When i try to initiate SSH to C router I get:

no matching cipher found their offer: aes128-cbc,3des-cbc,aes192-cbc


the routers can SSH to eachother, and the firewalls can SSH to eachother


what set command for CLi to enable SSH  for admin profile?


I'm not worried about GUI's at the moment, I am beginning to learn PA, this is a lab, and I'm writing scripts to interact with CLI commands.
