This is interesting, I was getting all kinds of weird behaviour on several domains, which I now managed to get rid of by disabling the brotli slider and removing the php.ini directives. Using Nginx + Cloudflare proxy, the WP single-signon from the panel would fail, and sometimes the domain root (and the domain root only....) would have trouble resolving.
I´ll leave it off until changing the slider takes care of everything properly, without having to mess with directives and options and possible conflicts.
