Aiohttp server exception

I get a single aiohttp.server exception when Home assistant restarts
It has been going on for a bit (unsure how long), the setup currently is:
Home Assistant 2023.1.4
Supervisor 2022.12.1
Operating System 9.4
Frontend 20230110.0 - latest

I have run it having removed all HACS integrations and the same exception occurs - is there any way of finding out more info on this exception - there is no other stack info in the log as it is at the moment that would help narrow it down… (any other logging changes I should make then repost?)
