Comment on Um... I'm not even using a VPN... Fuck you reddit.

I have also been getting this, via forced DNS over HTTPS (DoH).
You know, a basic security procedure that keeps you safer and more private than 95% of VPNs?
When they’re saying ‘blocked by network security’, they mean ‘your connection is too secure for us to easily deanonymize you’.

Can you enlighten me how that would work, as that makes no sense to me from a technical standpoint?
I feel to see how Reddit would be able to know how you are communicating with a random recursive resolver on the internet. Or are you running your own recursor and trying to use DoH to access their authoritative servers?

I am not running my own recursor, I am not scraping Reddit.
I have one browser that forces DNS over HTTPS and one that doesn’t, and the one that doesn’t, also I have yet to encounter this ‘security warning’ with.
???
Also to technically, how would this work?
It is early in the morning and I am too tired to posit a precise theory/explanation, but I also now realize I forgot to specify that my DoH setup is Oblivious DNS over HTTPS, ODoH… ie, all DNS requests and responses are routed via proxies.
So… basically, to Reddit, that may look like I am basically using a VPN, as there is no direct link from my actual IP to Reddit.

Ah, sounds like the issue is not DoH in that case, that would be impossible for Reddit to detect if you are using a browser. I suspect a domain gets blocked in one of your proxies, or Reddit returns alternative records to recursors they know are being used for privacy reasons.
