    your server's DNS resolver isn't working properly make sure DNS servers are working in /etc/resolv.conf
    won't help if you server's DNS resolver isn't working first. You have removed the old custom zlib via nginx recompile, just didn't get to restart services, so probably easier to reboot server, then run centmin.sh menu option 4 and then manually check binaries/services have switched back to system zlib library via 2 commands mentioned in this thread.

    All good now :)

    Guess what?

    When i was trying to apply the fix OVH was updating my rack Network Maintenance and disconnect for a minute my server :whistle:

    Now i restart it and recompile and i verify with the above commands and all looks good :)

    Thank you !

    Eva, did you made benchmarks of Zlib 1.2.11 against Cloudflare Zlib 1.2.8?

    Nope.
    Cloudflare Zlib is quite useless as replacement system wide, because it is meant for web services. Secondly if you are replacing default CentOS Zlib with Cloudlare. A lot of base CentOS apps must be rebuild. Because most apps depends on Zlib. Also critical apps for example OpenSSL.

    no no just nginx is meant to use custom zlib 1.2.11 or cloudflare zlib library and this is what this thread's zlib workaround fix is for. To ensure other services use system yum provided zlib and not the custom zlib 1.2.11 or cloudflare zlib library - hence why the service restarts are needed (or ccache recompile)
