iOS Client not connecting via Local Address (Manual setup; Public Address OK)

Hi,

When on wifi, the iOS Client is not connecting anymore to the "Local Address" (http & https).

Configuration is "Manual".

-> When on 4G, the app is connecting successfully via the "Public Address" (http).

-> When on wifi, I can successfully browse to the IP address set in the "Local Address" (http & https).

The issue started 2-3 days ago...

Below some extra info :

• iOS App version : 4.8.3
  

• iPhone 13 Pro / iOS 15.1.1
  
• iPhone 11 Pro / iOS 15.0.2

• Server version : 4.8.20

Already restarted the server...

Any suggestion ? Something I can test ?

Thank you
