Weird error in syslog - open() "/usr/local/www/robots.txt" failed (2: No such file or directory)

Hi!

I'm running PfSense 2.4.5-RELEASE and I see these errors in the log file:
It's some kind of request to open a robots.txt file for some reason but I'm not initiating this (manually). Robots.txt is used to give the search engine robots directives.

Is it possible that this is initiated by some kind of browser extention?
Do you guys have seen anything similar?

The request is coming locally, from 192.168.20.102 and 192.168.20.112. It's something on one of those systems, you'll have to look at those to see what is running on them. Beyond that, there is no way to tell from the log what it is. Any number of things could be doing it.

@jimp Ok clear. I will monitor what is specifically happens from that IP and dig a little deeper. Thanks for the swift reply.
