Note that especially Google Chrome has the tendency to cache SSL certificates for a while. So even after replacing the SSL certificate, it can take some time for it to be visible. Using the regular browser cache clearing features do NOT clear this particular cache. But you can bypass this cache by checking your website in Incognito Mode.
I see you switched your certificate from Let’s Encrypt to Google Trust. Both are perfectly valid certificates, but Google Trust has slightly worse browser acceptance rates in my experience than Let’s Encrypt.
