Hi and welcome to the forum.
I'm not sure what you're asking about. Are you setting-up something like this? https://thingsboard.io/docs/samples/esp ... mperature/
Is this the guide you mentioned? https://www.qnap.com/en/how-to/tutorial ... suite-lite

Hi icapelli,
Can you help check if your NAS IP has ever changed?
If you have changed your IP, go to "Setting page > Administrative Settings" renew your IP Address.
And edit your code to new IP addriss.
Thank you.
