I get this message when I try to Check for Available Updates:
"Unable to fetch available updates data - unexpected HTTP response code."
I get this message when I try to update the language pack:
"Unable to connect to the download server. It is not possible to install or update the language packs automatically. Please download the appropriate ZIP file(s) from https://download.moodle.org/langpack/3.3/ and unzip them manually to your data directory"
And when I tried installing/updating a plugin (such as Coupon) from Moodle.org:
"There is a request to install plugin Coupon (block_coupon) version 2017092500 from the Moodle plugins directory on this site. However, the plugin installation pre-check failed (reason code: remoteunavailable)."
Any suggestions, please?
I'm using Moodle 3.3.2+, PHP 5.6
