I have an issue with proton. I hosted the software on my own homeserver with portainer.

Often it comes the failure “TypeError: NetworkError when attempting to fetch resource.”

when i try to upload images

or

when I try to post something

in photon. It doesnt work in Firefox (Mac) or Safari (iOS, MacOS).

The instance is not the problem. It works with voyager.

      Errors are definitely indicating CORS is the issue. Specifically, that the Access-Control-Allow-Origin header is missing:

      Grund: CORS-Kopfzeile 'Access-Control-Allow-Origin' fehlt). Statuscode: 503.

      Are you perhaps (accidentally) stripping out that header in your NPM config? Or do you have a browser extension that might be doing so?
