The env section referenced a REQUEST_URI

/favicon/proxied?XXXX.ico

I checked the URL XXXX.ico and it’s valid and working and returns the site ico image, tt seems to be referring to the site logo icon. I noticed anytime I open any page on the forum this error is logged.

What is this error, what it mean and how does one fix it?

Not sure if it’s related but I also saw this error just above in the logs referencing the same icon URL, but it’s only been logged twice, about 2 weeks ago
