Hey Arne,
This is what I know for Mendix cloud servers, that they enable TLS in all network calls, currently they support version 1.2. You can raise support ticket and ask about the roadmap of releasing version 1.3.
Thanks & Regards,
Naman Khard

Dear Customer, Thanks for contacting Mendix Support. If you see from our release notes, our Mendix Cloud has supported TLS 1.3 since February 2020: https://docs.mendix.com/releasenotes/developer-portal/mendix-cloud/#tlsv13-support-for-mendix-cloud-all-regionshttps://docs.mendix.com/support/security-findings-faq/#81-weak-ciphers-supported-in-mendix-cloud We do support TLS 1.3. It's just that we also support TLS 1.2. If your client supports TLS 1.3, it will automatically use TLS 1.3. As not all clients support TLS 1.2, we also support TLS 1.2 for compatibility.
