Thank you Pedro. Below I found the answer…

Hey there! This task has been a time sink for me, and it’s not because I couldn’t find the answer. HTB’s lingo got me: “Submit the entire banner as the answer.” I thought it meant more than just the version. But guess what? Don’t submit the full banner—just the SMB version listed under “VERSION.” Save time and effort, folks! Happy hacking!
