Hello Sir / Madam,
I am facing a problem when submit DOI from Crossref Export Plugin (OJS-3.1.1.4). Showing this below error.
Please see the screenshot.
OJS Version- 3.1.1.4 PHP Version- 7.3
Submission was not successful! The DOI registration server returned an error: '1 - HTTP/1.1 100 Continue HTTP/1.1 400 Bad Request server: Apache-Coyote/1.1 crossref-deployment-name: ds5-2 content-length: 0 date: Mon, 14 Jun 2021 05:02:21 GMT permissions-policy: interest-cohort=() connection: close
Perhaps you could try that and let me know if it works?
And, just a note, that the version of OJS that you’re using (3.1) is no longer supported by PKP. I recommend that you upgrade to the newest version of OJS, as there are some improvements in OJS and the Crossref plugins that you may wish to take advantage of. Along with that, you may wish to upgrade your Crossref plugin.
I would recommend the upgrade. But you might want to review the Crossref guide to ensure that you have everything configured correctly: Crossref OJS 3.2+ Manual
Additionally, as I suggested in my previous posts, ensuring that your credentials are correct may address the issue (although I can’t say for sure).
