From a4e63e5a47a855884ae3aea41dfbfa464bddb744 Mon Sep 17 00:00:00 2001 From: Julian Fietkau <1278511+jfietkau@users.noreply.github.com> Date: Wed, 23 Sep 2020 12:14:08 +0200 Subject: [PATCH] Add note to reverse_proxy.md about disabling Apache's mod_security2 (#8375) This change adds a note and a few lines of configuration settings for Apache users to disable ModSecurity for Synapse's virtual hosts. With ModSecurity enabled and running with its default settings, Matrix clients are unable to send chat messages through the Synapse installation. With this change, ModSecurity can be disabled only for the Synapse virtual hosts. --- changelog.d/8375.doc | 1 + docs/reverse_proxy.md | 8 ++++++++ 2 files changed, 9 insertions(+) create mode 100644 changelog.d/8375.doc diff --git a/changelog.d/8375.doc b/changelog.d/8375.doc new file mode 100644 index 000000000..d291fb92f --- /dev/null +++ b/changelog.d/8375.doc @@ -0,0 +1 @@ +Add note to the reverse proxy settings documentation about disabling Apache's mod_security2.
