I’ve tried to register content for one of our journals via the OJS Crossref export plugin, but have run into a 401 error. _Registration was not successful! The DOI registration server returned an error: ’(401 Unauthorized)'._ I’ve tried submitting the XML on the crossref administration platform, but I’ve run into another error message about “not being authorized to submit”. I’ve tested re-depositing another journal’s DOI and it does not seem to be a member issue, but only an issue with this one prefix/user. This user has been depositing DOIs for years without a problem until now. I saw another person having the same trouble in our forum, the crossref team was able to help them. How should I proceed? Thank you, Giulia ---

Thanks for that information. That member account, Revista Ciencia em Extensao – RCE, currently does not have permissions to register new DOIs. You’ll need to contact their sponsoring organization, ABEC Brasil, for more information about that. ---

Thank you, Shayn. Could you please check if that prefix does also not have a permission? Prefix: 10.32929 Thanks, Giulia ---

Dear Crossref Support Team, Thank you for confirming our Crossref membership and assigning us the DOI prefix 10.63995. I have a journal operating on the OJS platform, and I have registered the membership credentials in the Crossref plugin accordingly. However, I am encountering an error when attempting to register DOIs for articles. The system returns the following message: Registration Error Message: (401 Unauthorized) “There has been a problem locating a publisher for this DOI. Our system shows no member with the prefix 10.63995.” I have also attached a screenshot of the error for your reference. Could you please help us resolve this issue? It appears there may be a mismatch or delay in activating the DOI prefix or linking it to our membership account. We would appreciate your guidance on how to proceed. Thank you for your support. ---

Hi @fusionproceedings team, Thanks for the question. A 401 error in OJS usually means that there’s a problem with the credentials you’re using to deposit metadata with us. These credentials are set up through the screen in OJS shown in Step 3 at [this page](https://www.crossref.org/documentation/register-maintain-records/ojs-plugin/). ![A screenshot of the OJS plugin's setup page. There are four fields; Depositor name, Depositor email, Username, and Password. The Username is in the form of "email address/role".](https://us1.discourse-cdn.com/flex020/uploads/crossref/original/2X/4/433f442ea5a09e41fc5474274366367a590382c8.png) The 401 error usually comes about as a result of folks just entering their email address, rather than their email address **and role** to the Username field. Can you confirm that your username is in the form of `email@domain.tld/role` and that your Password is the same password you set up when I completed your account setup last week? Once all of this is updated, please retry a deposit and let us know if you’re still encountering this 401 error.
