I’ve been using LE for quite some time without any issues. However …
Today I tried to add a certificate for a new domain and it failed for the following reason:
Failed authorization procedure. promentorfinans.se (http-01): urn:acme:error:unauthorized :: The client lacks sufficient authorization :: The key authorization file from the server did not match this challenge [7aniy-jiMmzp5Qi7TD9TD2O7Fi7JXzVzt33_8yzgwyA.K50uFwf8ZXDR6ymNZ8Xjujxw9i3YOPCuL05RBECjTCU] != [7aniy-jiMmzp5Qi7TD9TD2O7Fi7JXzVzt33_8yzgwyA.-f_daEYxVOFls4aupfol2f4PA8ikqBUw-4tU6dotcK8]
I’m on CentOS7 w/ Apache 2.4.
I’ve checked the DNS/IP/A records and they are all good.
The vhost config is automated and I’ve been using this template for +100 certificates.
I use letsencrypt-auto when issuing the certificates but now I’ve tried the method suggested by your documentation, certbot --apache … and I’ve tested various other combinations including --certonly but they all end up with the above error.
I even tried deleting another certificate and there was no problem re-installing it.
Any help is greatly appreciated, thank you.
