My Server is hardwired to the main router via a gigabit switch. I already stated that above in the thread:
I already reinstalled everything 2 days ago as I stated here.
I did not restore from backup. I did:
Reinstall macOS
Reinstall Roon Server
Reinstall Roon Remote on all iOS devices.
Benjamin, I am not exactly sure you read the entirety of this thread, and frankly I am disappointed.
It has already been 5 days since I logged this, and all that has been done is going back and forth.
Can you please, in all honesty, review the info provided, rather than copy/paste pre-made actions that I have already taken in due diligence in the hopes to resolve the issue myself.
