Hello, I have been using Tvheadend for a long time (10+ years). I cannot remember if I did this in the past but when I try to get into the admin side of Tvheadend by logging in webui over VPN, I always get "403 Forbidden" error message. Getting to webui is not a problem. Problem only occurs when I click "Login" to administrate. Logging in when at home has no issues.
It is easy to recreate the steps. Go outside of local network. Connect over VPN (tried Wireguard and OpenVPN through TP-Link ER605 router) to the local network with Android phone. Use Firefox or Chrome, go to local webui, click "Login", put correct username and password.
Is this a Tvheadend configuration issue or is there something I have to change in VPN settings to allow me to administrate Tvheadend over VPN?
