+## (Backward Compatibility Break) Changing how reverse-proxying to Synapse works - now via a `matrix-synapse-reverse-proxy-companion` service
+
+**TLDR**: There's now a `matrix-synapse-reverse-proxy-companion` nginx service, which helps with reverse-proxying to Synapse and its various worker processes (if workers are enabled), so that `matrix-nginx-proxy` can be relieved of this role. `matrix-nginx-proxy` still remains as the public SSL-terminating reverse-proxy in the playbook. `matrix-synapse-reverse-proxy-companion` is just one more reverse-proxy thrown into the mix for convenience. People with a more custom reverse-proxying configuration may be affected - see [Webserver configuration](#webserver-configuration) below.
+
+### Background
+
+Previously, `matrix-nginx-proxy` forwarded requests to Synapse directly. When Synapse is running in worker mode, the reverse-proxying configuration is more complicated (different requests need to go to different Synapse worker processes). `matrix-nginx-proxy` had configuration for sending each URL endpoint to the correct Synapse worker responsible for handling it. However, sometimes people like to disable `matrix-nginx-proxy` (for whatever reason) as detailed in [Using your own webserver, instead of this playbook's nginx proxy](docs/configuring-playbook-own-webserver.md).
+
+Because `matrix-nginx-proxy` was so central to request forwarding, when it was disabled and Synapse was running with workers enabled, there was nothing which could forward requests to the correct place anymore.. which caused [problems such as this one affecting Dimension](https://github.com/spantaleev/matrix-docker-ansible-deploy/issues/2090).
+
+### Solution
+
+From now on, `matrix-nginx-proxy` is relieved of its function of reverse-proxying to Synapse and its various worker processes.
+This role is now handled by the new `matrix-synapse-reverse-proxy-companion` nginx service and works even if `matrix-nginx-proxy` is disabled.
+The purpose of the new `matrix-synapse-reverse-proxy-companion` service is to:
+
+- serve as a companion to Synapse and know how to reverse-proxy to Synapse correctly (no matter if workers are enabled or not)
+
+- provide a unified container address for reaching Synapse (no matter if workers are enabled or not)
+  - `matrix-synapse-reverse-proxy-companion:8008` for Synapse Client-Server API traffic
+  - `matrix-synapse-reverse-proxy-companion:8048` for Synapse Server-Server (Federation) API traffic
+
+- simplify `matrix-nginx-proxy` configuration - it now only needs to send requests to `matrix-synapse-reverse-proxy-companion` or `matrix-dendrite`, etc., without having to worry about workers
+
+- allow reverse-proxying to Synapse, even if `matrix-nginx-proxy` is disabled
+
+`matrix-nginx-proxy` still remains as the public SSL-terminating reverse-proxy in the playbook. All traffic goes through it before reaching any of the services.
+It's just that now the Synapse traffic is routed through `matrix-synapse-reverse-proxy-companion` like this:
+
+(`matrix-nginx-proxy` -> `matrix-synapse-reverse-proxy-companion` -> (`matrix-synapse` or some Synapse worker)).
+
+Various services (like Dimension, etc.) still talk to Synapse via `matrix-nginx-proxy` (e.g. `http://matrix-nginx-proxy:12080`) preferentially. They only talk to Synapse via the reverse-proxy companion (e.g. `http://matrix-synapse-reverse-proxy-companion:8008`) if `matrix-nginx-proxy` is disabled. Services should not be talking to Synapse (e.g. `https://matrix-synapse:8008` directly anymore), because when workers are enabled, that's the Synapse `master` process and may not be serving all URL endpoints needed by the service.
+
+### Webserver configuration
+
+- if you're using `matrix-nginx-proxy` (`matrix_nginx_proxy_enabled: true`, which is the default for the playbook), you don't need to do anything
+
+- if you're using your own `nginx` webserver running on the server, you shouldn't be affected. The `/matrix/nginx/conf.d` configuration and exposed ports that you're relying on will automatically be updated in a way that should work
+
+- if you're using another local webserver (e.g. Apache, etc.) and haven't changed any ports (`matrix_*_host_bind_port` definitions), you shouldn't be affected. You're likely sending Matrix traffic to `127.0.0.1:8008` and `127.0.0.1:8048`. These ports (`8008` and `8048`) will still be exposed on `127.0.0.1` by default - just not by the `matrix-synapse` container from now on, but by the `matrix-synapse-reverse-proxy-companion` container instead
+
+- if you've been exposing `matrix-synapse` ports (`matrix_synapse_container_client_api_host_bind_port`, etc.) manually, you should consider exposing `matrix-synapse-reverse-proxy-companion` ports instead
+
+- if you're running Traefik and reverse-proxying directly to the `matrix-synapse` container, you should start reverse-proxying to the `matrix-synapse-reverse-proxy-companion` container instead. See [our updated Traefik example configuration](docs/configuring-playbook-own-webserver.md#sample-configuration-for-running-behind-traefik-20). Note: we now recommend calling the federation entry point `federation` (instead of `synapse`) and reverse-proxying the federation traffic via `matrix-nginx-proxy`, instead of sending it directly to Synapse (or `matrix-synapse-reverse-proxy-companion`). This makes the configuration simpler.

+# matrix-synapse-reverse-proxy companion is a role which brings up a containerized nginx webserver which helps with reverse-proxying to Synapse.
+#
+# When Synapse is NOT running in worker-mode, reverse-proxying is relatively simple (everything goes to `matrix-synapse:XXXX`).
+#
+# When Synapse workers are enabled, however, the reverse-proxying configuration is much more complicated.
+# Certain requests need to go to certain workers, etc.
+# In the past, the main reverse proxy (`matrix-synapse-reverse-proxy-companion`) was handling request routing to the appropriate workers,
+# but that only worked well for external requests (from outside of the Matrix server itself).
+#
+# Without the help of `matrix-synapse-reverse-proxy-companion`, internal services (like Dimension) that would like to talk to Synapse over the container network
+# did not have an endpoint for Synapse that they could be pointed to and have it just work.
+# If `matrix-synapse-reverse-proxy-companion` was enabled, Dimension could be pointed to its vhost handling Synapse and routing to the appropriate workers,
+# but when `matrix-synapse-reverse-proxy-companion` was disabled, this helpful functionality was not available and the best we could do
+# is point Dimension to the main Synapse process at `matrix-synapse:XXXX` itself.
+# Doing that breaks requests that need to go to specific workers.
+# See: https://github.com/spantaleev/matrix-docker-ansible-deploy/issues/2090
+#
+# What this role does is, it extracts all the Synapse request routing out of the `matrix-synapse-reverse-proxy-companion` role here,
+# and makes the `matrix-synapse-reverse-proxy-companion` container service represent Synapse and route appropriately,
+# regardless of whether workers are enabled or disabled.
+# All other playbook services can then forget about `matrix-synapse` or `matrix-synapse-whatever-worker`, etc.,
+# and just use `matrix-synapse-reverse-proxy-companion` as their request destination.
