Invalid HTTP method Errors

Home assistant has been stable for me for a while,so I have not been as active looking at my logs. Today when looking I found consistent errors every 20 seconds or so like this

2020-06-23 17:08:38 ERROR (MainThread) [aiohttp.server] Error handling request
Traceback (most recent call last):

aiohttp.http_exceptions.BadStatusLine: invalid HTTP method

I will say that I recently configured NGNIX, and cloudflare, and switched to my own domain. While searching i found a few comments that seemed to make me believe it may be my configuration. But here is the part I’m struggling with. I have two HA instances, one is my main,and one is a test bed. Both of these are accessible through cloudflare to my NGNIX proxy. My test bed HA instance is not receiving the errors, which leads me to believe that one of my components is the issue. Problem is i dont know how to check to see which component is causing this issue. I’d prefer not to have to remove them all to find out. Can anyone tell me how to narrow down which component may be the culprit.

EDIT: i removed and readded a few componets such as spotify with no change. Additional info, the errors start appering with in the first 5 seconds of a restart and continue every 10-15 seconds therafter

Just adding to my own post in case it ever gets figured out how to determine what specifically is causing the error.

I did a few things today that made no difference.
I stood up a new NGNIX proxy on my router. So now the NGNIX Proxy is not local to either install of HA.
I went into cloudflare and tried a few DNS options (Proxied vs DNS only), and SSL scrict vs not strict.

Both HA instances are running the 111.4, they do not have all the same components but are pretty close.

I also removed and reconfigured Spotify and IFTTT.

Still the same error above every 5-10 seconds, with the first entry happing within the first 5 seconds of a restart.

I’ve just completed a fresh installation of HA core on a fresh installation of raspbian os lite and I got that error just for running hass … I didn’t even opened the web interface.

Are you using NGNIX?

I don’t think, it’s not even installed.
I just write the raspian os lite image on a micro sd, put there the “ssh” file to log on my headless rbpi and followed this guide https://www.home-assistant.io/docs/installation/raspberry-pi/
