OJS 2.4.8.1 Automatic DOI deposition of Crossref not working

HI
The crossref plugin is working only if i register the issues or articles manually it only take a second to get register and the username and password are working fine

all the info i read online regarding the requirements for the plugin to work automatically when i publish an issue or article are met…

yet whenever i give it a try it always give me (not deposit) status

I have tried everything but still not working … do u have any suggestions?

Thanx a lot

This is happening now for us too. Have to manually deposit all DOIs. This is NB for us. We are on version 3.1.2.1.
