Rendering failed with "error=dial tcp :0: connect: connection refused"

[rtoenniges]

What happened: After updating Grafana to v8.3.3 the "Image renderer plugin" doesn't work anymore.

I've enabled/increased every logging option i've found but this is all information I could get: t=2021-12-23T15:04:11+0100 lvl=info msg=Rendering logger=rendering renderer=plugin path="d-solo/R8ariy4nk/virtual-machines?orgId=1&refresh=1m&from=1640257253745&to=1640268053746&panelId=7&width=1000&height=500&tz=Europe%2FBerlin" t=2021-12-23T15:04:11+0100 lvl=eror msg="Rendering failed." logger=context userId=1 orgId=1 uname=admin error="dial tcp :0: connect: connection refused" t=2021-12-23T15:04:11+0100 lvl=eror msg="Request Completed" logger=context userId=1 orgId=1 uname=admin method=GET path=/render/d-solo/R8ariy4nk/virtual-machines status=500 remote_addr=192.168.2.40 time_ms=2 size=1344 referer=

How to reproduce it (as minimally and precisely as possible): It happens everytime I want to render a graph via "share" and "alert".

Anything else we need to know?: The plugin is listening correctly tcp LISTEN 0 128 127.0.0.1:43513 0.0.0.0:* users:(("plugin_start_li",pid=10381,fd=19))

I've tried to set the IP and Port to "0.0.0.0:8080" which works fine but the error is still the same.

Grafana is installed directly and not in a docker. In grafana.ini all render plugin options are set to default.

I've also disabled SELinux and firewalld temporarely but with no effect.

Environment:

• Grafana Image Renderer version: 3.3.0
• Grafana version: 8.3.3
• Installed plugin or remote renderer service: plugin
• OS Grafana Image Renderer is installed on: AlmaLinux 8
• User OS & Browser: Windows 11 / Chrome

there was a shared library added to the dependencies that we missed libxshmfence1 after that things started working again.

Hi! Is this issue still present with latest Grafana and image renderer? Does the suggestion above solve your issue?
