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.”
or
in photon. It doesnt work in Firefox (Mac) or Safari (iOS, MacOS).
The instance is not the problem. It works with voyager.
On my Homeserver runs an NGINX Proxy Manager. There is HTTPS activated. The proxy use HTTP to connect to the local Docker Container.
Internet --> NGINX Proxy Manager --> local Docker Container
The Instance discuss.tchncs.de is not mine, but I have set the enviroment “PUBLIC_INSTANCE_URL=discuss.tchncs.de”.
The errors are paste here
Errors are definitely indicating CORS is the issue. Specifically, that the
Access-Control-Allow-Originheader 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?
