CrossRef plugin submission OJS 32: No response from server

Hi,

We use OJS 3.2.1.3.

We encounter a problem with the CrossRef plugin. When we submitting XML, there is an error “No response from server.”

Credentials have been verified and the XML can be deposit directly on https://doi.crossref.org/

Is the API endpoint https://api.crossref.org/v2/deposits still working ?

Thanks in advance for your answer.
Best regards.

Hi again,

Hi @jalperin, @bozana, @jmacgreg, as authors identified of this plugin I hope you don’t mind if I ask you directly about my problem with the CrossRef plugin.

Any suggestions ?

Thanks in advance for your answer.
Kind regards
Helene

Hi Helene. The last time I did work on that plugin must have been a decade ago. I’ve asked a colleague to respond.

Hi Helene, without seeing how your plugin is set up, it can be tricky to troubleshoot. There have been no issues of late with the v2 API, as far as I know. It might be an issue with outgoing traffic in your server configuration? Typically, if the issue is credentials based, you’ll see a 403 error. If Crossref were fully down, you could check https://status.crossref.org/ to confirm. But, I would guess that this has to do with outgoing traffic. How long ago did you move to 3.2.1.3? Did you have a working plugin on this installation prior? Has anything changed?

Best,
Mike

Hi,

We use this plugin since 6 years and had no particulary problem. We didn’t make any change lately. So I didn’t understand where the problem came from.

As you confirmed there was no problem with the plugin, I investigated further on the error obtained. As there was no error reported in the log file, I added the curl function error : curl_error($curlCh) in the CrossRefExportPlugin.inc.php file. I could discover it was an expired certificate error which I updated and everything worked again after.

Thanks for answering me and trying to help me.
Best regards.
Helene
