Can't reach Web UI in HA #121

Closed Sundown89 closed 2 years ago

Sundown89 commented 2 years ago

Describe the bug After putting my HA instance behind a reverse proxy I can't reach the Web UI anymore. Config was filled before and I could create backups to NC successfully with a fresh install. Now I can't change the config anymore. Logs say nextcloud connection failed, so I want to review and change the config. Error message when opening Web UI says: addressofha.duckdns.org refused connection. Reverse Proxy is Caddy, not Nginx. HA is on a VirtualBox VM.

Expected behavior Open Web UI correctly so I can review and change config.

Found it.

In my case this had to do with my Caddy reverse proxy config, the X-Frame-Options header in particular. This was set to DENY and therefore it denied access to an iFrame from https://my.domain.com, what this addon seems to use. Changed it to X-Frame-Options "ALLOW-FROM https://my.domain.com" and it works now.
