Hi there

at some point in updating, somewhere around 1. of July, our subscription form has stopped working when being requested from another domain.

newsletter-2/:1 Access to fetch at 'https://listmonkdomain/api/public/subscription' from origin 'https://otherdomain has been blocked by CORS policy: Response to preflight request doesn't pass access control check: No 'Access-Control-Allow-Origin' header is present on the requested resource.

The Settings do not seem to include means to whitelist a domain. GPT suggests this is handled in a configuration.toml file, which does not exists and the Listmonk-Docs mention the configuration might be handled in the env-file.

If someone might have an idea how Listmonk handles CORS-related issues on Cloudron, I would be very happy.

Hello @Laktasekampagne

CORS can be configured in the app view in the Cloudron Dashboard.
If you supply the exact CORS error, I may be able to help with the CORS setting that needs to be added.

I put a note here about CORS - https://github.com/knadh/listmonk/discussions/2579

CORS should come from the app and not from the platform . Some of the rules pasted in their own GitHub issues are dangerous and should not be put in the reverse proxy without understanding the implications .
