🐞 Describe the bug

Using a self hosted installation version 2.14 behind Traefik I have HomePage set to link to NTFY Web and have authorised to HomePage using PocketId for local Authentication.
This creates some cookies which are passed around at domain level but seems to break NTFY communication with error 431 Header Fields Too Large.

💻 Components impacted

NTFY Web App is impacted

🔮 Additional context

Not sure why this is important to NTFY and whether the header issue can be addressed easily!

Closing this issue - not 100% sure if this is due to NTFY or Authelia inconjunction with NTFY but I have resolved the issue using a Plugin withn Trefik.
