GLIBC problem on Linux server

Inmotionhosing recently switched my server from a Centos 7 machine to one running AlmaLinux. My web apps run, but do not output anything to a browser. Their support says there is an issue with GLIBC in that the current version, 2.28, not being compatible with my app. All their servers are x64 and the Xojo docs say anything after 2.14 should work. Is the new version not compatible with Xojo?
