Drakma on Ubuntu

Hi,

   I earlier asked for suggestions for connecting Lispworks to Ollama LLMs. Thanks to all the advice, I was able to settle on Drakma to make that connection work on MacOS. I’m working on putting the code I wrote which calls Drakma into a single file so others can use it too. But I’ve run into a problem porting that code from Lispworks 8.01 MacOS Sequoia 15.7.3 to Lispworks 8.01, running on Ubuntu 22.04.3 LTS.

    Calling Drakma in MacOS like this:

(drakma:http-request "https://example.com"
                     :method :get
                     :parameters '(("query" . "drachma") ("format" . "json"))
                     :user-agent "Mozilla/5.0 (compatible; MyLispBot/1.0)")

;  Returns the expected results:

200
((:DATE . "Tue, 14 Jul 2026 20:47:32 GMT") (:CONTENT-TYPE . "text/html") (:TRANSFER-ENCODING . "chunked") (:CONNECTION . "close") (:SERVER . "cloudflare") (:LAST-MODIFIED . "Wed, 01 Jul 2026 17:50:18 GMT") (:ALLOW . "GET, HEAD") (:ACCEPT-RANGES . "bytes") (:AGE . "88") (:CF-CACHE-STATUS . "HIT") (:CF-RAY . "a1b36214ecb899f9-IAD"))
#<PURI:URI https://example.com/?query=drachma&format=json>
#<FLEXI-STREAMS:FLEXI-IO-STREAM 8080002A9B>
T
"OK"

But making the same call in Ubuntu, I get this error:

CL-USER 1 > (drakma:http-request "https://example.com"
                     :method :get
                     :parameters '(("query" . "drachma") ("format" . "json"))
                     :user-agent "Mozilla/5.0 (compatible; MyLispBot/1.0)")

Can anybody suggest how I can fix this bug? I’ve upgraded Drakma and openssl on my Ubuntu laptop, to the latest versions, but the error persists.

Best,

Lawrence Au
