Hi @BessemAamira,

Is your server firewalled from contacting pkp.sfu.ca? It’ll be necessary to permit OJS to contact pkp.sfu.ca to check for updated versions and compatible plugins. (If you need to set up a proxy, it can be configured in config.inc.php.)

Good Evening,

My server is our DMZ and prevents any outbound connections. Can I somehow disable my OJS install to connect to pkp.sfu.ca as I cannot open the Administration page

Thanks
Daan

Hi @daanlessing,

To turn off outgoing connections from OJS to the PKP server, turn off enable_beacon and show_upgrade_warning in config.inc.php.

There are other outgoing connections you may need, e.g. for CrossRef deposits; if you have a proxy, you can configure it in config.inc.php.

Hi asmecher and all.

Our test server (private network) is suffering the same problem after the installation from 3.3.0.6 to 3.3.0.8
Setting the show_upgrade_warning variable resolved the problem but i tried also to set proxy parameter without much success.

http_proxy = “http://proxy.xxx.yy:8080”
https_proxy = “http://proxy.xxx.yy:8080”

GuzzleHttp complains very much. Do you know the right string for proxy conf ? i read/tried also tcp://proxy.xxx.yy:8080 …

Best regards,
Paolo

In my case, It was due to the Selinux mode. To fix/debug this issue, you can switch selinux to permissive mode
