Vitotrol 300-E connectivity failure (with Vitodens 222-f)

I have one Vitodens 222-f, and one wired Vitotrol 300-E.

I explained in an email to Viessmann UK support on 14.07.2023...
"I can't say for sure, but I think the reason the Vitotrol has been disconnected
from my system is because of a recent software update."
 
About 10 emails later....the 300E still won't connect to my boiler, and Viessmann UK doesn't want to tell
me that a Viessmann boiler firmware update has turned my 300E controller into an expensive paperweight.
 
So to save me further wasted time, can someone from Viessmann Germany simply tell me 
which wired controller I now need to buy, which will operate like a 300E, but work with my 222-f

Thank you.
