Certificate Authority Issue Maybe?

I have a custom TankUtility app that's been running for several years without issue, suddenly now it can no longer communicate. The example here works in a browser but no longer works from the Hubitat hub. Could this be a certificate authority issue? I can see in the browser their certificate is issued from "SSL.com RSA SSL subCA."
Here's the Hubitat error from the log:
javax.net.ssl.SSLHandshakeException: sun.security.validator.ValidatorException: PKIX path building failed: sun.security.provider.certpath.SunCertPathBuilderException: unable to find valid certification path to requested target

Example of the request:
https://data.tankutility.com/api/devices?token=AMf-vBw8f5_kTPVrOk3MMk3Z0k2G14k6KFyoiaRq5...

likely should send a note to tank utility folks

Update: It looks like TankUtility changed their certificate. By using the parameter "ignoreSSLIssues" (which I wasn't aware of until now) the requests now work. Since the requests work fine from a PC, I'm wondering - is there a way to add a certificate/certificate authority to a hub?
