Failed to lookup IPv4 address of MYCHECKMK_SITEvia DNS: [Errno -3] Temporary failure in name resolution
My Steps:
Now, i have the right “RootCA” on my checkMK Server. I switch in /etc/apache27sites-enable/000-default.conf to the Rewrite Rule like the checkMK Doku
Note: In the Checkmk appliance, you enable [HTTPS via the web interface!]
Done
I get a “new” error Msg on any Webbrowser (testet wth Brave/Chrom and firefox) ERR_SSL_PROTOCOL_ERROR
Ok, i dig arround and i found the OMD Commands, i do:
cmk --debug -vvn MYCHECKMK_SITE - and as a result
Failed to lookup IPv4 address of MYCHECKMK_SITE via DNS: [Errno -3] Temporary failure in name resolution
it’s clear for my: “MYCHECKMK_SITE is not a DNS Entry on my DNS Server”
what would you do?
Hint: “I haven’t been doing this since yesterday, but the checkMK way is a bit strange for me.”
