sun.security.validator.ValidatorException: PKIX path building failed

Got this error when saving a specific page:

Traceback (most recent call last):

LiveDocumentNotAvailableException: javax.net.ssl.SSLHandshakeException: sun.security.validator.ValidatorException: PKIX path building failed: sun.security.provider.certpath.SunCertPathBuilderException: unable

The code I'm using:

import savepagenow

archive_url, captured = savepagenow.capture_or_cache("https://www.chp.gov.hk/files/pdf/local_situation_covid19_tc.pdf")
print(archive_url)

The same code works for some other URL normally.

I presume this is a server side error because I don't think this library is calling Java on my workstation. Strangely, if I post on the Save Page Now form, it actually creates a snapshot of the URL. What is going on?

The URL I'm trying to archive: https://www.chp.gov.hk/files/pdf/local_situation_covid19_tc.pdf

To me this reads like some kind of SSL issue with your web request from the script.

Is there any option to circumvent the SSL error from blocking the program?
