This causes problems with simplepie parsing headers when adding RSS feeds when Moodle is behind a proxy. For example; https://www.nasa.gov/rss/dyn/earth.rss (which responds with HTTP/2 200). Effectively hitting what was reported in MDL-38170
Original report below:
Hello,
Since i have upgrade my Moodle to 3.10.5+, from time to time, i've got this message from my Moodle Cron :
PHP Notice: Undefined index: content-type in /var/www/lib/simplepie/library/SimplePie.php on line 1648
No errors detected from scheduled tasks. No interesting logs from the Moodle interface or from the server.
Has anyone seen this problem before ?
PS : my server is behind a web proxy
