Log Error 400, message=“Bad status line ‘Expected CRLF after version’”

Configuration

Hi to all,

I’m running the latest Home Assistant in a VM on a Proxmox server (i5 6400, 16gb RAM) and it was running quite fine until latest update.

After upgrading from 2023.4.6 to 2023.5.2 I started getting this error in the logs:

Logger: aiohttp.server
Source: /usr/local/lib/python3.10/site-packages/aiohttp/web_protocol.py:403
First occurred: 09:02:50 (5199 occurrences)
Last logged: 09:28:29

Traceback (most recent call last):
  File "/usr/local/lib/python3.10/site-packages/aiohttp/web_protocol.py", line 332, in data_received
    messages, upgraded, tail = self._request_parser.feed_data(data)
  File "aiohttp/_http_parser.pyx", line 551, in aiohttp._http_parser.HttpParser.feed_data
aiohttp.http_exceptions.BadStatusLine: 400, message="Bad status line 'Expected CRLF after version'"

At the moment eveything seems to be working fine but the number of occurrences of the error keeps increasing significantly every time I check the logs.

Is anyone else having the same problem?
Any idea what could be the cause?

Thank you in advance

Same here. We should log an issue, but I have no idea where to log it, but I will log it under core.

I, also, found this issue and it appears it is an issue if you have Hikvision devices with an older firmware.
