AppImage worked though. (Same build)

ownCloud 5.0.0.11120-daily20230531 cf17cd
Libraries Qt 6.4.3, OpenSSL 1.1.1t 7 Feb 2023
Using virtual files plugin: suffix
ubuntu-5.19.0-43-generic

Libraries OpenSSL 1.1.1t 7 Feb 2023 is missing in the version information from the broken build ⚠️

@fmoc builds shouldn't succeed without OpenSSL

I'll check whether qt for windows was build without openssl 😅

[TheOneRing]

Sooo our msi installer installs just a couple of plugins and the tls openssl plugin, thats new with qt6, isn't one of them.

We need to test the installer for regressions

Tested with ownCloud 5.0.0.11369-daily20230703 511b96
Connection to oCIS server can be made ✔️
