Make http2 work with an nginx and apache setup

I'm migrating from ionos to aws and need to keep the existing architecture the same (old wordpress instance with a lot of custom business-specific code). On the new server (aws), I have nginx proxying to apache built with php-cfm for wordpress running on amazon linux 2 (centos based). Both nginx and apache share the letsencrypt certificate. On the old server (ionos) running on ubuntu, http2 works fine: curl -lv [login to view URL] > /dev/null On the new server (aws), we have an error with http2: curl -lv --resolve '[login to view URL]:[login to view URL]' [login to view URL] > /dev/null I'm looking for someone with a lot of experience with setting up nginx/apache on centos (or amazon Linux) and able to fix this particular issue.
