Hi! Since there's no dedicated forum for the website and it affects my ability to upgrade MobileSheets Companion, I chose to post here.

In both Firefox and Chrome, https://www.zubersoft.com/mobilesheets/companion/ looks quite broken because resources loaded from https://zubersoft.download are blocked by the browser as the certificate for that site has an unknown issuer (SEC_ERROR_UNKNOWN_ISSUER). For the same reason, the download of MobileSheets Companion is also blocked by the browser.

It looks pretty fishy to me that zubersoft.com has a Let's encrypt certificate, but zubersoft.download uses a (from what I can see) self-signed certificate. Is this intentional?

What you are seeing is strange - I don't get that at all through Chrome or FireFox. It loads properly for me. As far as the certificates, I use LetsEncrypt for my server (www.zubersoft.com), but www.zubersoft.download is a Cloudflare bucket that I use as a CDN to ensure downloads are quick across the entire world (as my server is located in the US). CDNs are pretty normal. As far as the certificate, something seems wrong with your setup. I just looked in FireFox, and it shows that zubersoft.download has a certificate issued by Google Trust Services (Common Name WE1), so that is definitely not a self signing certificate.

On a side note, you can get the companion app directly from my server if you prefer: https://www.zubersoft.com/mobilesheets/M...panion.exe

Thanks for the quick and helpful response!

I noticed that my ISP DNS-blocks zubersoft.download for some reason. Using different DNS servers makes everything work again.
