I've tried to request a new certificate for another domain on the same server.
That isn't working either. I guess due to the same reason.
Enabled "disable LE check" and checked LE again in the domain after.
LE is checked now, but the certificate still isn't renewed.
Already updated ISPC to 3.1.6 and tried disabling and re-enabling LE before and after the update several times.
Every time I see the same in the logs.
I've setup a perfect server with Ubuntu 16.04, apache 2.4, MariaDB 10, ISPC 3.1 etc.
ISPC is running several websites without problems for some...
