Hi @Surojit_Bera,

Here is posts of users encountering similar errors here and addressing them here (though verifying their crossref credentials): CrossRef XML Explort Plugin - DOI Submission error - #2 by bozana

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.

Upgrading instructions are available in the PKP Administrator’s Guide .

Information about the latest version of OJS can be found on the [PKP Website]

The Crossref documentation can be found here: Crossref OJS 3.2+ Manual

Hello @rcgillis
Any other option without upgrade OJS. Because my mysql DB size is approx 400MB.

I think this problem comes from crossref plugin… any updated crossref plugin for version

Hi @Surojit_Bera,

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).
