Hey Yann,
Saw your post in the other Local Import ERROR thread. There are a few things to check:
- Verify that nothing changed in the config for your LOCAL_URI_SERVER setting. It should be set to "By default (http://localhost:80/ocsinventory)". I believe your "internal dummy" connections in the log you posted may cause this to happen.
- Check your configuration settings in the /etc/apache2/*.conf files.
This is a starting point for things to check. I can't exactly tell by what you posted what the cause of your issue could be.
Questions for you - What OCS server version did you upgrade from? Did you do any other changes along with the upgrade (i.e upgrade Apache, change IP / DNS, change access to the server (http/https/other port))?
