A client of ours has a website that works on most browsers. However, when trying to open it in Chrome (114), Edge (114) or Samsung Internet (21) on Android, there is an error message saying
Your connection is not private ERR:ERR_CERT_AUTHORITY_INVALID.
We tried several phones with Android 12 and 13, but the results are all the same.
- Firefox on Android works
- Chrome and Safari on iPad and iPhone work
- Chrome, Edge and Firefox on Windows desktop work
Because it works in almost all browsers, I think it's safe to assume there is nothing wrong with the certificate, and the problem lies with Chromium.
My question is, how can I further investigate this issue?
(I realize this question may not necessarily be about Android, but I'm not sure where else to post it)
