I found that my Discourse cannot generate OneBox for any websites except YouTube, when checking out the log, I saw this error thrown:

Tested `Oneboxer.onebox('https://bilibili.com')` invocation in `rails c`, then getting the same error.
I do not know why and feel puzzled now, because Discourse can process OAuth and AI request and other HTTP requests with no errors, it only happened to OneBox, but YouTube OneBox can be normally generated.
It was using a proxy server now and I am sure that this is not proxy’s problem, `curl`, `wget` and `httpx` module in Python could fetch response successfully, but `excon` in Ruby gave me `SSL: wrong version number`, what should I do to fix it?
I used `3.0.13` release of OpenSSL, which was published in Jan. 2024, when compiling the Ruby interpreter, is that version too old?
