Hi everyone,
I’m trying to figure out TLS/root-certificate compatibility on older LG webOS TVs (mainly 2017/2018-era sets, typically webOS 3.x / 4.x).
We have a webOS Web App (WebView-based) that talks to our backend over HTTPS. We recently moved one of our API/CDN hostnames to a newer certificate chain (DigiCert “G2/G3 family”). On newer TVs everything is fine, but on some older LG TVs we start seeing weird behavior: users can often log in after clearing cookies, but logout/profile switching fails and the requests don’t seem to reach our servers (so it smells like a TLS validation / trust-store issue rather than just an app bug).
I’m hoping someone here has concrete info on these points:
-
Do 2017/2018 LG webOS TVs normally trust DigiCert Global Root G2 / G3?
If not, is there a known firmware/webOS version where this starts working? -
Are root CA updates tied to firmware updates on LG TVs, or is the trusted root set basically “fixed” per model year?
-
If anyone has an older webOS TV handy: could you try opening these URLs in the TV browser and tell me whether they load or show a cert error?
-
https://global-root-g2.chain-demos.digicert.com/ -
https://valid.x1.test-certs.letsencrypt.org/(Let’s Encrypt / ISRG Root X1)
-
-
If G2/X1 don’t work on those models, what are people doing in practice to maintain HTTPS compatibility? (Different CA roots, legacy hostnames, anything else?)
If it helps, I can share example user-agent strings, model numbers we’re seeing, and exact symptom/repro steps.
Thanks in advance!
