Zimbra webmail not working on port 80/443
On Zimbra mail server, webmail stopped working on Port 80/443. Admin interface worked properly on url https://hostname:7071/. There is no errors displayed under monitor tab of Zimbra Admin.
To fix, run
su - zimbra zmprov ms `zmhostname` zimbraReverseProxySSLToUpstreamEnabled FALSE zmprov ms `zmhostname` zimbraMailMode both zmprov ms `zmhostname` zimbraReverseProxyMailMode both ./libexec/zmproxyconfig -e -w -o -a 8080:80:8443:443 -x both -H `zmhostname` zmcontrol restart
After running this, netstat -lntp start showing nginx running on port 80 and 443
