I found out what the issue with this is, at least for me.
Using the built in browser in Steam, I can reliably reproduce this error when browsing the Darkest Dungeon wiki. Not always, but it definitely seems related to an ad/popup or redirect or some sort of (undesirable call/action); one which I never experience with Chrome itself since I run Ublock Origin.
So for those of you getting the error in Chrome itself - you may want to run Ublock Origin (which is generally a good idea anyways, and, yes, you can disable it on a site by site basis if you want).
I’ll take a guess that the 0.0.0.0.0 IP is due to some hosts file customization? Maybe an AV product has added records or makes changes? That’s the one thing I don’t have any visibility or experience with.
