the developers are doing important work. hopefully, one will stop by.
fwiw, your issue seem straightforward enough and you seem not to take the time or effort to solve it on your own.
reading the rclone debug log output, reading rclone documentation and a simple internet search, would provide the answers...
have you done that yet?
Wow. That’s really helpful thank you.
wow, you are really welcome

Since direct SMB and crypt via the SMB backend both work fine, the hang seems specific to how crypt handles the mounted filesystem. Might be worth checking what's actually happening on the destination during that pause — see if there's disk activity or if it's blocked on something else.
The internal ssh library tries to use secure protocols only. Any of the older insecure protocols are disabled.
My guess is that the incompatibly is somewhere there
The ssh client has lots of options though!
To try to narrow things down I'd try connecting with rclone with -vv -dump bodies to see more info and connecting with the standard ssh binary with -vvvvv to get it to output exactly how it is connecting.
This might also be a bug in the nas or the ssh Library.
