I can’t connect Epson ET-2850 to Smart Hub Plus

[HenryTudor8]

I’m going in ever decreasing circles. I set up an Epson ET-2850 a week or two ago and everything was fine. Then a couple of days ago the wheels came off. I have a Mac Mini running OS Sequoia and I run NordVPN. 

I saw a message flash up on the screen that appeared to say that an IP address (local network) had been blocked. No time to read it fully before it went. Since then I can’t connect my printer. I’ve spent the best part of two days and can’t fix it. I wonder if the hub has blocked the MAC address. 
I’ve done everything other than reset the hub.

Any ideas please and the wisdom of resetting the hub.

many thanks.

@AL0602 : Which SH? The SH (2023), SH+ or the SH Pro? What colour is it?

On the SH+ it's on L centre.
