Original Pull Request: https://github.com/jellyfin/jellyfin/pull/12094

State: closed
Merged: Yes


Kestrel in dual-socket mode will always serve IPv4 addresses as IPv6 mapped, making our checks fail.

Changes

  • Check if address is IPv6 mapped IPv4 and map back to IPv4
  • Use IsLoopback for more reliable loopback checks

Issues
Fixes #11968
