I have other domains running nicely over _ttps__ (SSL from LE) and renewal is in operation. Two more sites using subdomain and they receive the certificates nicely. But two sites fail to renew their certificates. The new certificates are created with an extra www. added and I can't understand why? These two sites host Atlassian Confluence and Atlassian Jira applications both running on localhost. But why is the SSL certs created with an extra added www_? What could be causing this? Example: _ttps__gyro_chemovix_com receives certificate _ttps__www_gyro_chemovix_com which of course is not valid. More information: Ubuntu Linux 18_04_1 Linux 4_15_0-50-generic on x86_64 Current ISPConfig3 settings: IP-Address: * (on all sites) Domain: gyro_chemovix_com CGI = Yes Auto-Subdomain = None SSL = Yes Let's Encrypt = Yes but returns unticked PHP = CGI Re-direct type = L SEO Redirect = www_domain_ltd => domain_tld Rewrite HTTP to _ttps = Yes SSL Domain = *_gyro_chemovix_com Apache Directives: <Proxy *> Order deny,allow Allow from all </Proxy> SSLProxyEngine On ProxyRequests On ProxyPreserveHost On ProxyPass / _ttp__127_0_0_1:8080/ ProxyPassReverse / _ttp__127_0_0_1:8080/ I have no _htaccess for these sites. The Server Base URLs are correctly set in Atlassian application. SSL was actually running before renewal failed. I, maybe, desperately changed something but without success. Or other sites were added that reveal the true error that was there from start. I do have A record for DNS set as: gyro_chemovix_com_ (with trailing dot) Any hints and tips are welcomed. Thanks.
