I have ispconfig servers running nginx. When I updated from 22.214.171.124 to 126.96.36.199 I choose to reconfigure services. During this operation, the phpmyadmin links were removed from the nginx config (ispconfig.vhost). I see that there is an apps.vhost on port 8081 that has those apps. I don't remember (actually lost some notes) whether my install is not standard or if this was changed at some point in ispconfig. ispcomm.
