Hello everyone. Yesterday I decide to upgrade my server and my Moodle installation but I'm having some trouble upgrading or installing new plugin.
Server is a VPS hosted on OVH, with Debian 8 and Plesk installed, since last year. Moodle version was 3.8.
So, yesterday as first thing I upgraded the OS to Debian 9, then upgraded Plesk with latest version (18.0.33) and MariaDB to a supported version, and finally Moodle to version 3.10. I also had to change the domain of the site, to reflect the new company name. Doing this Plesk changed also the internal folder where all file reside but I simply updated the url on the config.php file and everything seems to working smoothly. But I had some trouble trying to upgrade the plugin, or install new one or re-register the site on the hub, because every time I do one of this operation i get an HTTP 503 error. Reading other topic in this forum, I tried doing a curl from the shell of the server, which, as expected, returned the same error:
curl -I https://moodle.org/plugins/
HTTP/2 503

Doing the same command on my machine, return instead code HTTP/200.
I'm start to thinking that my server could be banned from CloudFare? It is possible? What can I do?
Thank you every one.
