Https Access with Wildcard certificate

Configuration
1

I use a Wildcard certificate (letsencrypt) as SSL certificate for all my home services to get rid of https issues.
Infact I had no problems with my config the Last year.
But since one of the last Android updates I could no longer access my HA installation with the Android app.
Issues: certification authority iscnot trusted!
But: all my Other Services are working with my certificate! (e.g. nextcloud and Others)
Access via browser is working, iOS App is still working (but havn’t updated!)

Any Ideas?

Do you get “site not trusted” or it just fails? Any error code?

Clear browser cache?

Try this

No, in fact, I can’t use the Android App anymor.

IT stopped working in all of my Android devices!
So, I’m pretty sure, it’s my configuration.
I suspect the News versions of the Android App need the fullchain pem certificate now?

Problem solved,
I just replaced the wildcard certificate (which was working till January) by the full chain certificate (which also was generated automatically by my pfsense acme plugin).
