Original report:
Getting this error when trying to view direct link rendered image.
Timeout error. You can set timeout in seconds with &timeout url parameter
You can easily reproduce this from the PMM demo link:

It never seems to complete even when increasing timeout.
The current solution for rendering this image is PhantomJS but it's deprecated already. The workaround is to use Grafana image renderer instead: https://grafana.com/docs/grafana/latest/administration/image_rendering
$ docker exec -it pmm-server bash
# grafana-cli plugins install grafana-image-renderer
# yum install libXcomposite libXdamage libXtst cups libXScrnSaver pango atk adwaita-cursor-theme adwaita-icon-theme at at-spi2-atk at-spi2-core cairo-gobject colord-libs dconf desktop-file-utils ed emacs-filesystem gdk-pixbuf2 glib-networking gnutls gsettings-desktop-schemas gtk-update-icon-cache gtk3 hicolor-icon-theme jasper-libs json-glib libappindicator-gtk3 libdbusmenu libdbusmenu-gtk3 libepoxy liberation-fonts liberation-narrow-fonts liberation-sans-fonts liberation-serif-fonts libgusb libindicator-gtk3 libmodman libproxy libsoup libwayland-cursor libwayland-egl libxkbcommon m4 mailx nettle patch psmisc redhat-lsb-core redhat-lsb-submod-security rest spax time trousers xdg-utils xkeyboard-config alsa-lib
# exit
$ docker restart pmm-server
Perhaps we can adopt this new solution or provide documentation or fix to get direct rendering via PhantomJS working on-the-fly.
Tech details:
PhantomJS will be removed in Grafana 7, so there is no option to fix it. it needs to be replaced
