Original GitHub issue: https://github.com/langchain-ai/docs/issues/1676

Type of issue

issue / bug

Language

Python

Description

Several pages under the LangChain Python API documentation domain are currently inaccessible due to SSL protocol failures.

Example URL (but not the only one affected):
https://api.python.langchain.com/en/latest/document_loaders/langchain_community.document_loaders.pdf.UnstructuredPDFLoader.html

When attempting to open these pages, the browser returns:

This site can’t provide a secure connection
api.python.langchain.com uses an unsupported protocol.
ERR_SSL_VERSION_OR_CIPHER_MISMATCH

This affects multiple documentation endpoints, not just the one listed above. The issue appears to be related to misconfigured SSL on api.python.langchain.com.

Please investigate and fix the SSL configuration so the documentation becomes accessible again.

those are dead/old URLs - would ask where you are finding them?
