Thank you. I will back soon after tests.

Hi @Sandeep B. Did you find any solutions to this issue? Kindest regards: TheHolbi

Hi @Sandeep B. do you find any solutions to handle this issue?

Other data: The HTTP2 installation deletes the mod_security2.so file from the modules folder. And if mod_security is installed again, it will incompatible and won't load.

Hi @Sandeep B. The process in the tutorial was tested in an other CWPPro instance of my services. The mod_security was installed on the server before this test. The error appeared after running Goto Apache Settings >> Apache Re-Build >> Select Next : Next delete/replace all with this flags/lines under “Additional configuration” (the config was changed properly) -- then Click on Start Compiler in background.

OK, thank you. Is there a special reason to use Nghttp2 version 1.42.0, and not the latest, available Nghttp2 v1.59.0 in the tutorial? It is true, the Nghttp2 v1.59.0 dropped the support old OpenSSL (< 1.1.1) but we uses 1.1.1u in the build and it can be good.

Hi @Sandeep B. Thank you for the tutorial. It works in a newly installed VPS powered by CWPPro. The only issue is: The installed mod_security (CWP admin panel) brakes the httpd.service with HTTP2 protocol and produced the following error lines: What do you suggest? How to handle it?
