Trying to append postgres-exporter's reverse-proxying configuration to matrix-nginx-proxy,
|
|
but it's pointless since the matrix-nginx-proxy role had already executed.
|
|
To fix this, please change the order of roles in your playbook,
|
|
so that the matrix-nginx-proxy role would run after the matrix-prometheus-postgres-exporter role.
