no matching cipher found
means sever , client offers different ciphers.
client side:
debug2: kex_parse_kexinit: blowfish-cbc,arcfour server side:
debug2: kex_parse_kexinit: chacha20-poly1305@openssh.com,aes128-ctr,aes192-ctr,aes256-ctr,aes128-gcm@openssh.com,aes256-gcm@openssh.com the client side proposal not default values, because unsafe ciphers (disabled on sane server). should check /etc/ssh/ssh_config , remove line
ciphers blowfish-cbc,arcfour or similar (regardless how , why there). if need legacy ciphers connect legacy systems, there match block, can use
match legacy.hostmane ciphers blowfish-cbc,arcfour
