SonicOS 7 and CORS (cross origin resource sharing)
In the office, we have troubles with website Kaart | Geldmaat Locatiewijzer
It shows up partially, no ability to look up locations. At home it works fine. So it's probably something with the TZ470 we have. It doesn't show any errors or warnings. Using the Developer Tools in Edge shows what's the problem:
Access to XMLHttpRequest at 'https://lrxs9ggm8j.execute-api.eu-west-1.amazonaws.com/prod/locations?fields=id&fields=latitude&fields=longitude&fields=functionality&fields=audioGuidance&fields=withdrawableDenominations&fields=geldmaatPlus' from origin 'https://www.locatiewijzer.geldmaat.nl' has been blocked by CORS policy: No 'Access-Control-Allow-Origin' header is present on the requested resource.
It seems like the firewall is stripping the HTML header? Is there any way to resolve this?
