2531	You cannot use variables in error_log and ssl_certificate	EduardoRuizM@…		"Variables defined by SET are not processed internally

SAMPLE:

set $DOMAIN ""mydomain.com"";
error_log       /mypath/$DOMAIN/logs/error.log;
ssl_certificate         /mycerts/$DOMAIN/fullchain.cer
ssl_certificate_key     /mycerts/$DOMAIN/$DOMAIN.key;


No problem with access_log and you can use:
access_log       /mypath/$DOMAIN/logs/access.log main;
