Hello @Djaber_T, thank you for posting to our Qlik Community! Was it working at some point before? There could be multiple root cause to this issue, could you please have a look at the following article? https://community.qlik.com/t5/Knowledge/Advanced-troubleshooting-of-the-GRPC-and-or-CEF-Error-Issues/ta-p/1806741

Hi @Patricia_Silva no it's a fresh install so it never worked

i have tried many points you shared in your response (root cause) but with no positive result i still have the problem

Do you have any other ideas?

Regards

@Djaber_T

If you are still having image rendering issues, make sure to follow the steps in this article.

https://community.qlik.com/t5/Knowledge/NPrinting-Qlik-Sense-Images-Fail-to-Render-Export-Generate-or/ta-p/1713381

If this doesn't solve it, then please submit a support request.

Note: Make sure that you check that the image tags in your report are not referencing an outdated or no longer available object. This can happen if for example a chart was deleted then recreated but the NP designer uses the original tag.

In this case,

Delete the image tag in the NP report
Reload your NP connection
Find and re-add your image to the template
Preview the report

Kind regards...
