I would guess medium is blocking digitalocean ips, but i haven't looked into it at all.

I've started getting the same error on my home IP I can (sometimes) view articles locally.

I think it's trying to pull GetPostLight in https://git.batsense.net/realaravinth/libmedium/src/branch/master/schemas/query.graphql:

query GetPostLight($id: ID!) {
    post(id: $id) {
        uniqueSlug
        creator {
            username
        }
    }
}

The closest query I could find in a successful article load (warning long):

Did they change their schema? Are they fingerprinting and rejecting queries? Is this rejecting clients who didn't pass a Cloudflare challenge at cdn-cgi/challenge-platform/h/g/precursor/...?

it's cloudflare.

            client: Client::builder()
                .user_agent("User-Agent: Mozilla/5.0 (X11; Linux x86_64; rv:153.0) Gecko/20100101 Firefox/153.0")
                .connection_verbose(true)
                .build()
                .unwrap(),

err_safe.html (google says it's a WAF block?)

discussion on why at https://github.com/seanmonstar/reqwest/discussions/2227

Could you try enabling the http2 feature and also native-tls-alpn if you're using native-tls?

it seems http2 is no longer present (always on?) and native-tls-alpn was integrated into regular native-tls (https://docs.rs/reqwest/latest/reqwest/). enabling features = ["json", "native-tls"] did not fix the issue. Running samply record target/debug/libmedium shows stack traces referencing hyper. I'd say this means native-tls wasn't applied... except request's source code comments say default-tls "it currently uses native-tls"... idk

Additionally it seems reqwest issues a http/1.1 request?

I tried:

[dependencies.graphql_client]
features = ["reqwest"]
version = "0.16.0"

[dependencies.reqwest]
features = ["json", "native-tls-alpn"]
version = "0.12"

and we successfully fetch over http2, but still error out. sigh.

it's not the user agent; Bruno without user agent succeeds yet Reqwest with UA fails.

curl

curl 'https://medium.com/_/graphql' \
  --compressed \
  -X POST \
  -H 'User-Agent: Mozilla/5.0 (X11; Linux x86_64; rv:153.0) Gecko/20100101 Firefox/153.0' \

removing User-Agent triggers the WAF error
removing graphql-operation triggers an interstitial (presumably thinks it's a HTTP request not graphql op?)

reqwest http1

[dependencies.reqwest]
features = ["json"]
version = "0.12"

actually logs website content! ...and fails anyway. despite the Cloudflare response having Content-Type: application/json; charset=utf-8 and a pile of data. i think it's a bug in our client somehow. Probably should debug it at some point...

EDIT: i'm past the blocking period, but it seems browser user-agent without browser headers gets nuked? but curl still requires the browser UA to not get nuked...

it's cloudflare. ```rust client: Client::builder() .user_agent("User-Agent: Mozilla/5.0 (X11; Linux x86_64; rv:153.0) Gecko/20100101 Firefox/153.0") .connection_verbose(true) .build() .unwrap(), ``` [err_safe.html](/attachments/ee45e364-71af-4daa-8887-3860c77c291a) (google says it's a WAF block?) discussion on why at https://github.com/seanmonstar/reqwest/discussions/2227 > Could you try enabling the `http2` feature and also `native-tls-alpn` if you're using native-tls? it seems http2 is no longer present (always on?) and native-tls-alpn was integrated into regular native-tls (https://docs.rs/reqwest/latest/reqwest/). enabling `features = ["json", "native-tls"]` did not fix the issue. Running `samply record target/debug/libmedium` shows stack traces referencing hyper. I'd say this means native-tls wasn't applied... except request's source code comments say default-tls "it currently uses `native-tls`"... idk Additionally it seems reqwest issues a http/1.1 request? I tried: ```toml [dependencies.graphql_client] features = ["reqwest"] version = "0.16.0" [dependencies.reqwest] features = ["json", "native-tls-alpn"] version = "0.12" ``` and we successfully fetch over http2, but *still* error out. sigh. it's not the user agent; Bruno without user agent succeeds yet Reqwest with UA fails. ### curl ```sh curl 'https://medium.com/_/graphql' \ --compressed \ -X POST \ -H 'User-Agent: Mozilla/5.0 (X11; Linux x86_64; rv:153.0) Gecko/20100101 Firefox/153.0' \ -H 'Accept: */*' \ -H 'Accept-Language: en-US,en;q=0.9' \ -H 'Accept-Encoding: gzip, deflate, br, zstd' \ -H 'content-type: application/json' \ -H 'graphql-operation: VisitorQuery' \ -H 'Origin: https://medium.com' \ -H 'Connection: keep-alive' \ -H 'Sec-Fetch-Dest: empty' \ -H 'Sec-Fetch-Mode: cors' \ -H 'Sec-Fetch-Site: same-origin' \ -H 'Priority: u=4' \ -H 'TE: trailers' \ --data-raw '[{"operationName":"VisitorQuery","variables":{},"query":"query VisitorQuery {\n visitor {\n id\n geolocation {\n country\n __typename\n }\n __typename\n }\n}\n"}]' ``` - removing User-Agent triggers the WAF error - removing graphql-operation triggers an interstitial (presumably thinks it's a HTTP request not graphql op?) ### reqwest http1 ```toml [dependencies.reqwest] features = ["json"] version = "0.12" ``` actually logs website content! ...and fails anyway. despite the Cloudflare response having `Content-Type: application/json; charset=utf-8` and a pile of data. i think it's a bug in our client somehow. Probably should debug it at some point... **EDIT:** i'm past the blocking period, but it seems browser user-agent without browser headers gets nuked? but curl still requires the browser UA to not get nuked...

I've assembled a working fork at https://git.batsense.net/nyanpasu64/libmedium/src/branch/fix (is your fingerprint SHA256:wUP77yJCCoTnbTu6LkYp2as3NzsZTIjfVWwllhcHkwY?).

I was able to successfully load /@wenting_zhang/getting-fluent-at-the-language-of-iconography-3415d03d0a8f. Though it does print a warning:

 INFO  libmedium::post       > Unknown type: SECTION_CAPTION

Strangely this caption appears in the JSON fetched by reqwest, and the DOM of the article at https://medium.com/@wenting_zhang/getting-fluent-at-the-language-of-iconography-3415d03d0a8f (window.__APOLLO_STATE__), but not in the actual text or alt-text visible in the browser. I decided to silence it, but don't know if this is the official website's behavior for all pages.

...looking at this page I think Scribe had better typography. you failed to add space between the blockquote and headings, since normally <p> handles margins but blockquotes lack them.

EDIT: turns out Scribe uses tufte-css:

nyanpasu64@servlet ~/code/scribe (main)> rg tufte  # (results reordered for clarity)
package.json
11:    "tufte-css": "^1.8.0",
