over the weekend, I’m getting this error message (Java 12) when trying to connect to a domain using a let’s encrypt certificate:
PKIX path building failed: sun.security.provider.certpath.SunCertPathBuilderException: unable to find valid certification path to requested target
Typically, this error message appears, when a self-signed certificate is being used - which is not the fact. I am quite certain, this started to be an issue over the last couple of days. Looking at the certificate, however I do not see a problem. It’s https://graph.homefully.tech
Does anybody have an idea what the problem could be?
there is a check of your domain, ~45 minutes old - https://check-your-website.server-daten.de/?q=graph.homefully.tech
looks good, the certificate
expires in 80 days *.homeful.ly, *.homefully.tech, homeful.ly - 3 entries
is new (but not created in the last days). But:
Chain - incomplete
Your server doesn't send the intermediate certificate. That may be the problem.
Should look like
2 CN=Let's Encrypt Authority X3, O=Let's Encrypt, C=US
thanks for the input! Indeed that solved the problem!
