Shopware Domain Mapping Misconfiguration Help

Solution:

1. Open the Administration
2. Click on the left bottom side on the desired sales channel
3. Make sure in the Domain Panel that the current access URL is added there: https://test-sw.uhlsport-csa3-dev.gbc.systems

Solution:

Make sure the visible URL is the actual URL in your browser: https://test-sw.uhlsport-csa3-dev.gbc.systems/. If not, the proxy configuration could be wrong.

Shopware got following headers from IP 216.73.216.10:
{ "Host": "test-sw.uhlsport-csa3-dev.gbc.systems", "X-Forwarded-Host": null, "X-Forwarded-Proto": null, "X-Forwarded-For": "216.73.216.10" }

The trusted_proxy configuration could look like this:
# config/packages/framework.yaml framework: # You can use multiple with comma separated values or subnet notation (10.0.0.0/8) trusted_proxies: '216.73.216.10' # trust *all* "X-Forwarded-*" headers trusted_headers: [ 'x-forwarded-for', ]
