What Grafana version and what operating system are you using?
Grafana 9.3.1 installed on Ubuntu 22.04 via apt-get -
What are you trying to achieve?
Simple reverse proxy without subpath -
How are you trying to achieve it?
Following the documentation Run Grafana behind a reverse proxy | Grafana Labs
With an nginx proxy -
What happened?
Grafana works well, but arround one of ten request (including requesting html, js, css, imgs, /api …) to the proxy fails with the following error :
upstream connect error or disconnect/reset before headers. reset reason: connection failure, transport failure reason: delayed connect error: 111
The http request that fails change at every reload, sometimes it can’t request the js files, sometimes the css and sometimes everything loads well but some /api request fails
-
What did you expect to happen?
All requests to the grafana server should succeed -
Can you copy/paste the configuration(s) that you are having problems with?
# grafana.ini (params that are not listed here are still commented
app_mode = production
[server]
http_port = 3000
domain = grafana.**********.com
# tried to enable/disable subpath
# nginx grafana.conf
map $http_upgrade $connection_upgrade {
default upgrade;
'' close;
}
upstream grafana {
server community.grafana.com;
}
server {
listen 80;

server_name grafana.****************.com;
location / {
proxy_set_header Host grafana.***************.com;
