Download Image In LAN Always failed

Hello everyone, I have a problem, I want to download an image in the LAN, but when I use the Download Image node, the download always fails. The URL I filled in is the URL of the LAN. But this URL can be accessed normally in chrome. Is it necessary to add additional settings to download images in the LAN? I am very anxious, I hope that good people can help me answer it, thank you all.
