Receiving ERR_INVALID_HTTP_RESPONSE - What have I done wrong?

*** SELF RESOLVED ***

Other service running on 32400 - bloody missed it.

Hey Guys,

Have had this for a few weeks and can’t think of anything that changed in my environment that may be causing this.

Accessing " http://127.0.0.1:32400/web/index.html " or any variant returns " 127.0.0.1 sent an invalid response.
ERR_INVALID_HTTP_RESPONSE "

I’ve completely removed plex ( registry entries, app data etc ) 3 times and reinstalled - each time I have success for a few days, then I start getting the above error. This is driving me insane and I can’t seem to find any info on it.

Logs attached.

What was the problem? I have the same one now…

I think he said what the problem was in the edit at the top of his post.
