I have an Problem on my 7.1.1 Master/Replica installation. When I restart the zimbra "zmcontrol stop" "zmcontrol start" nginx does not start anymore.

Starting nginx...nginx: [emerg] SSL_CTX_use_certificate_chain_file("/opt/zimbra/conf/domaincerts/mydomain.com.crt") failed (SSL: error:02001002:system library:fopen:No such file or directory error:20074002:BIO routines:FILE_CTRL:system lib error:140DC002:SSL routines:SSL_CTX_use_certificate_chain_file:system lib)

This happens after the first domain where added.
There is no "/opt/zimbra/conf/domaincerts/" folder on my system.
We have no idea why this happens, we don't use an domain certificate (for this installation we don't want any).

Have someone an idea how to fix this?
