Hello Tomas,  thank you for a quick response,  I upgrade the HTTP module in /usr/lib64/knot-resolver/kres_modules/ from Github source https://github.com/CZ-NIC/knot-resolver (https://github.com/CZ-NIC/knot-resolver) then I assume, that should be the latest one, unfortunately the output is the same Oct 08 11:29:31 dns_lab kresd[607]: error: /usr/lib64/knot-resolver/kres_ modules/http.lua:35: attempt to call global 'moduledir' (a nil value) Oct 08 11:29:31 dns_lab kresd[607]: [system] failed to load module 'http' Oct 08 11:29:31 dns_lab kresd[607]: error occured here (config filename: lineno is at the bottom, if config is involved): Oct 08 11:29:31 dns_lab kresd[607]: stack traceback: Oct 08 11:29:31 dns_lab kresd[607]: [C]: in function 'load' Oct 08 11:29:31 dns_lab kresd[607]: /etc/knot-resolver/kresd.conf:14: in main chunk Oct 08 11:29:31 dns_lab kresd[607]: ERROR: No such file or directory Oct 08 11:29:31 dns_lab systemd[1]: kresd(a)1.service: main process exited, code=exited, status=1/FAILURE Oct 08 11:29:31 dns_lab systemd[1]: Failed to start Knot Resolver daemon.

This looks very odd - it seems like an old version of the http module. Could you please check the version of knot-resover-module-http package and upgrade it if possible? -- Tomas Krizek PGP: 4A8B A48C 2AED 933B D495 C509 A1FB A5F7 EF8C 4869 "

Hello Tomas,  thank you. now I´m using an official build for both knot-resolver and knot-resolver- module-http knot-resolver-module-http-4.2.0-1.el7.x86_64 knot-resolver-4.2.0-1.el7.x86_64 It works now like a charm.

Mixing source files and packages is usually a really bad idea. And the http.lua.in file is a template that needs some further modifications by our build system. Just reinstall knot-resolver and knot-resolver-module-http package, ensure it's the correct version by: rpm -qa | grep knot-resolver And if that doesn't work, there might some some issue with our packages. This config works for me when I have the latest versions of both knot-resolver and knot-resolver-module-http packages on CentOS7. -- Tomas Krizek PGP: 4A8B A48C 2AED 933B D495 C509 A1FB A5F7 EF8C 4869 "
