Describe the bug

PDF preview/download/print does’nt work when access the selfhosed server via reverseproxy manger like NPM

Steps To Reproduce

Create a client from client tab, then go to invoice and select a product/service and scroll down in invoice section, pdf preview keeps on loading until it fails. Can’t get to print nor download or preview when we try to access it behind the NPM(nginxproxymanger). i’ve tried setting domain name and IP too in trusted proxy in ENV

Expected Behavior

I exepected it to load and able to download as it normally does when access the same page via direct IP address like 192.168.0.44:80.

Hi,

Are there any details about the error in storage/logs?

3

Hi, here are the logs from storage directory

@hillel

4

If you’re using the SnapPDF PDF generator you may want to try changing to hosted_ninja

5

Now i lost preview in both via proxy and directly via IP.

6

You may want to try using telnet from the server to check that the host/port is reachable

7

All my ports are free and i can very well reach with just ip and port

8

It may help to add TRUSTED_PROXIES=* to the .env file

9

its been added since default.
ill attach my compose and env.
