hi, I added a wildcard certificate on ispconfig 3.1.13 (6 centos) and from all subsites (and even the other sites who have no certificate) are redirected in https to the main site !! Example : *.mydomain.com is the wildcard certificate, https://subsite.mydomain.com are redirected to https://www.mydomain.com, and https://www.anotherdomain.com are redirected to https://www.mydomain.com In HTTP sites work normally. I added on the subdomains the certificate. How can I fix the problem ? Thanks for your help.
