Can’t connect to my NAS (Server).

Seems like every time I upgrade I loose my connection to my NAS when in the Files app on my iPad Pro 13” M4. When I try to “Connect to Server” and enter all the required information nothing happens - no connection. what is more interesting is that many times at some point all when I launch the Files app the NAS shows up. Clueless on that one - without me doing anything. I don’t have this problem with my iPhone 17 Pro Max or before my iPhone 15 Pro Max the NAS connects just fine. It is only my iPad Pro 13” M4 that has the issues and I can’t figure out why. I also use another third party app, FB, which is another files type app. it connects just fine. I also have a USB SSD connected to my ASUS router that connects via the Files app just fine also. It is only my NAS.

BTW, I built the NAS and use TrueNAS software. All other devices connect just fine. It is only my iPad Pro.

Any ideas on this one??
