Hi everyone,

I've enabled the mod_http2 by running this:

# yum remove ea-apache24-mod_http2 ea-nghttp2 ea-libnghttp2
# rm -fv /etc/yum.repos.d/EA4-mod_http2.repo
# yum downgrade 'ea-apache24*'
# yum clean all ; yum install ea-apache24-mod_http2

I've also added this lines to '/etc/apache2/conf.d/http2.conf'
<IfModule http2_module>
LogLevel http2:info
Protocols h2 h2c http/1.1
</IfModule>

However, i can never got h2 working on chrome, i only see only http1.1
Yes, my site is on https and it is working fine.

I saw this on the apache error log too, not sure if it is relevant

Hello @cywong89,

However, i can never got h2 working on chrome, i only see only http1.1
Yes, my site is on https and it is working fine.
A similar report from another user noted their issue was related to the NOD32 Antivirus application. Could you verify if you are using that application, or any other antivirus applications, on system used to access the website?

Thank you.

Hi, thanks for reply..
I am not using NOD32, however I do have bitdefender install on my system.
I am using nginx on my local development server and http2 is working fine.

Hello,

Can you temporarily disable BitDefender and verify if the issue persists? Also, could you confirm what Operating System you are using on the system where you are accessing the website?

Thank you.
