When visiting some sites on Cromite, Fennec, or IronFox on my Android devices, the Anubis challenge fails with the error “invalid response”. I don’t recall if there were any other error messages that came up. This only affects a seemingly random portion of sites using Anubis and does not clear up after refreshing, both immediately and after waiting several hours. It’s never affected Firefox and Librewolf on desktop, however.
Anyone know why it happens, how to avoid it, or what logs I could collect for an issue report on Github?
I had a similar experience with Cloudflare, for a period of time my Ironfox browser failed the challenge on one or two websites. I don’t remember if it happened with Anubis, I fear there are too many variables (e.g. extensions installed) so I’d like to know how to get helpful logs.
Interesting. The only extensions I have on my mobile browsers are adblockers (uBlock for IronFox and Cromite’s inbuilt adblocker)
