Firstly, please ensure the article has a DOI and the DOI you typed is correct.

Then, maybe some databases don’t offer DOI retrieval method. You can turn to other databases including DOI fields for help like Web of Science, Wanfang, etc.

Also we recommend you to change retrieval conditions like author, title, etc. (Detailed information can be inquired on crossref.org. or chinadoi.cn by DOI).
