DOIs problem in OJS

Hi All,

I try to deposit the article using CrossRef XML Export Plugin but face the following error.
Registration was not successful! The DOI registration server returned an error: ’ (401 Unauthorized)’.

I review the forum yet have not found an answer.
How can I solve that?

Hi @Gokmen_ARSLAN

A similar issue was resolved here: DOIs not deposited error in OJS 3.0.0 - #5 by bozana

I hope you find it useful


Thank you, Alejandra_Casas. I checked it. It seems okay. I also emailed Crosreff yet have not received any reply.
