+### Version information
+
+<!-- IMPORTANT: please answer the following questions, to help us narrow down the problem -->
+
+- **Homeserver**: Was this issue identified on matrix.org or another homeserver?
+
+If not matrix.org:
+- **Version**:        What version of Synapse is running? <!-- 
+You can find the Synapse version by inspecting the server headers (replace matrix.org with
+your own homeserver domain):
+$ curl -v https://matrix.org/_matrix/client/versions 2>&1 | grep "Server:"
