Ubuntu 20.04 LTS installed a 16GB KVM VPS.
Behind HAProxy on a PFSense box. HAProxy uses a 301 redirect from HTTP(80) to HTTPS (443). HAProxy hosts the LE certificate. There is no HTTPS enabled on the NC install itself.
Fresh NC install via snap.
When I login from Chrome/Edge, I get stuck on the “Login” Page. There is a console message of "Refused to send form data to ‘http://cloud.nydomain.com/’ because it violates the following Content Security Policy directive: “form-action ‘self’”.
If I refresh, I can access and use NC just fine. I have no problems on Firefox.
Any ideas?
