[MediaWiki-l] GuzzleHttp requires cURL, the allow_url_fopen ini setting, or a custom HTTP handler.

Hi Everyone, I'm using MW 1.35.1 release tarball. We migrated to a new VM using Ubuntu 20, x86_64, fully patched. I also updated composer dependencies. Below is a new error when we edit a wiki page and click Submit. Preview is OK. We did not experience it on our CentOS 7 VM during Submit. We are in a hardened state. We can't meet Guzzle's requirements because: open_basedir="/var/www/html/:/var/lib/php/" allow_url_fopen=Off allow_url_include=Off Looking at Special:Version, Guzzle is described as "Guzzle is a PHP HTTP client library." I don't believe our Mediawiki should be making outbound requests like this. We disabled Guzzle by disabling SpamBlacklist. This brings a couple of questions: * Why is Guzzle filtering Sysops or Administrator actions? * Is there another way to get the Spam blacklist? Like a Systemd service that runs once an hour? Thanks in advance. ========== [YGi84aU19iAalBwOJ8j4SAAAAAU] /w/index.php?title=Main_Page&action=submit RuntimeException from line 119 of /var/www/html/w/vendor/guzzlehttp/guzzle/src/functions.php: GuzzleHttp requires cURL, the allow_url_fopen ini setting, or a custom HTTP handler.
