aiohtttp error and web scanning from Censys Inc

[kroa38]

Hello,

I have this error since i installed HACS & Pyscript.

Logger: aiohttp.server
Source: /usr/local/lib/python3.13/site-packages/aiohttp/web_protocol.py:481

It seems that the IPs are related to Censys Inc a compagny specialised in the scan of internet !

HA OS version 2025.10.3
HACS V2.05
Pyscript 1.6.4

Any idea ?
Thanks

Pyscript doesn't call aiohttp unless you write pyscript code that does. Do you have any pyscript code that calls aiohttp, specifically does it start aiohttp.server? If not, then this issue doesn't relate to pyscript.

So it sounds like your pyscript's are not the culprit. It's impossible to tell what the issue or cause might be, and whether it relates to pyscript. The error is from inbound requests to an aiohttp server that is running. It looks like you don't have any firewall, which is not a good idea. It's no surprise that a public IP address will receive many inbound malformed requests.

I'd recommend you disable your pyscripts and see if the aiohttp server is still running after restart. You need to figure out which integration is starting the aiohttp server.
