Hi @BenWibking, the reason may be is that Agent is still using .Net Core 3.1, which requires OpenSSL 1.1 - #3834 (comment)
Could you check if libssl 1.1 is present on your machine?

[BenWibking]

No, it's not present. RHEL 9 (and derivatives) ship with OpenSSL 3: https://www.redhat.com/en/blog/experience-bringing-openssl-30-rhel-and-fedora. It should be documented that it's not compatible with RHEL 9 if that's the case.

[BenWibking]

This link says .NET 3.1 is compatible with RHEL 7+, which is just incorrect w.r.t. RHEL 9: https://github.com/dotnet/core/blob/main/release-notes/3.1/3.1-supported-os.md#linux

[KonstantinTyukalov]

Hi @BenWibking
we created a public ticket about status of agent migration to .net 6 - #3922

Let me close this issue then.
If you have any concerns, feel free to ask and we will reopen it.
