Exception when executing <save>

[MariMa_san]

When archiving the config via commit-archive an " [Errno 111] Connection refused" error occurs so I modified the config, also on Synology to get it running without success. Now I’m getting:

Archiving config…
scp://10.19.0.254:/volume2/technics/hosts/server/router/04.vyOS/vyOS - backup Unable to upload “scp://marima:[email protected]/volume2/technics/hosts/server/router/04.vyOS/vyOS - backup/config.boot-vyos.schniek.net.20250502_182849”: EOF during negotiation
run-parts: /etc/commit/post-hooks.d/02vyos-commit-archive exited with return code 1

When using scp directly to upload files to the NAS it is only possible when using scp with -O parameter
To check if it is in general possible to save on the NAS I executed

marima@vyos# save
Possible completions:

scp://user:passwd@host:/file Save to file on remote machine

marima@vyos#
marima@vyos# set system config-management commit-archive location
Possible completions:

scp://user:passwd@host/path

scp once with and once without colon? What is correct?

Tested with another remote server
=> Bad authentication type; allowed types: [‘publickey’]

With
=> PasswordAuthentication yes
in /etc/ssh/sshd_config it works…
