welp it works now, I think I’ll leave this up for future reference.
I think both PCs were running a browser extension Consent-o-matic (for removing cookies consent) that might cause issue. disabling the extension solved it.
Or maybe it just resolved itself after a few hours of my fiddling.

Basic Internet infrastructure has been erratic for a couple of weeks with an AWS outage and now a Microsoft outage. Both are very large hosting companies for companies like GF who do not run their own servers (or potentially your ISP as well). I don’t recall which GF uses for their servers but they’re undoubtedly affected. The route to their servers may also be impacted depending on your ISP (Microsoft is reporting DNS issues - the “how do I get there?” service that tells your browser how to find things).
