I updated the code and it works, the message no longer appears.
I didn't notice the missing 344 value either; even if I looked more carefully at the whois, I might have noticed it, damn it.
I'm glad, though, that it wasn't due to other scripts; it would have been a pain to find the cause.
Now I'll start testing the scripts in daily use, I'll see if there's anything else wrong, if everything's ok, if there are any gaps and so on. If so, I'll update this post.
Thank you so much for your effort @Epic, you're great, I really appreciated it.
