We recently updated our test OJS from 126.96.36.199 to 188.8.131.52.
One of the problems that occured is that the plugin gallery is empty. We have enabled
allow_url_fopen as suggested in another thread in this forum but it does not work anyway.
There is the following warning:
PHP Warning: fopen(https://pkp.sfu.ca/ojs/xml/plugins.xml): failed to open stream: Connection refused in /var/www/test.ojs.openagrar.de/lib/pkp/classes/file/FileWrapper.inc.php on line 70
My admin tells me, we use a proxy for internet connection and also, that the check for OJS updates is working. What settings should I check to ensure, that OJS can access the remote xml?
