Let's encrypt error

NethServer Version: 7.5.1804
Module: let’s encrypt

Hi all,

everthing worked fine until yesterday morning…I had bee the happiest nethserver-User ever!!!

But now everthing went wrong…

at the moment i get 502 Bad gateaway for my vhost

so I tried to connect only by http, without success so I tried to reactivate ssl for the vhost an thought to ask for a new certificate but i got this:

Failed authorization procedure. www.mydomain.de (http-01): urn:ietf:params:acme:error:unauthorized :: The client lacks sufficient authorization :: The key authorization file from the server did not match this challenge …

My server is called central.mydomain.lan
The vhost is www.mydomain.de(over selfhost.de to feste-ip.net, for portmapper and https-proxy, to my ipv6 router to my nethserver(ipv6-address)

Yesterday afternoon I installed some updates in nethserver, and after that(not sure, if it could be the reason…) I get the 502 Bad gateaway Error. And before that I tried to install nethserver-Wordpress but deinstalled it becasue of https problems with the .css ans .js files.

any suggestion for me to start my investigation

thx all

Did you try to restart apache?
Is there something at the logs?
I think httpd and messages log are the right one:
Have a look at


and all logs at
