Grafana shows "If you're seeing this Grafana has failed to load its application files"

Hi, i’ve installed grafana 7.3.6 on Windows Server 2019 (it’s the first time I want to run it on Windows).
As describe i have copied sample.ini to custom.ini and changed the port to 8080.
Than i startet grafana-server.exe and tried to open grafana in the browser using http://localhost:8080.

The following message is shown:
Grafana

If you're seeing this Grafana has failed to load its application files

1. This could be caused by your reverse proxy settings.
2. If you host grafana under subpath make sure your grafana.ini root_url setting includes subpath. If not using a reverse proxy make sure to set serve_from_sub_path to true.
3. If you have a local dev build make sure you build frontend using: yarn start, yarn start:hot, or yarn build
4. Sometimes restarting grafana-server can help

Actually i’m not familiar with proxy settings. so first i changed the setting serve_from_sub_path to true and restartet grafana-server.exe. But still the same message.

Can somebody know how to get grafana to run?

If there are some data that can help finding the cause let me know where to find them and I will post them.

Thanks

Hi,

Did you use the standalone installer ?

Good Luck

Hi, i used the standalone installer (grafana-7.3.6.windows-amd64.msi).

Just tried the following:

Downloaded the binaries (zip file) on a Windows 10 Enterprise machine, extracted it and run grafana-server.exe without any modifications on the config.
Worked out of the box.

Then copied the zip file on the Windows Server machine and tried the same.
But i get the same output (“If you’re seeing this Grafana has failed…”) in the browser.

Maybe the error is caused by the operation system?
I enabled the compatability mode for grafana-server.exe and run is as administrator.
But unfortunatelly this didn’t solve the issue.

Any ideas?

Tried to run older versions on the server.
Figured out that the versions up to 7.2.2 are running like expected.
The issue occures on 7.3.x versions.

Hi,

Weird but may be a bug introduced by this version, is anything logged in Windows Events (might be permissions or firewall rules …)

Good Luck

In the events there are only infos concerning starting and stopping grafana.
And in the grafana log file there are no errors logged.
