Hello, I have multiservers set up : 2 servers ns1 and ns2, with ubuntu 20.04 and ispc3.2 I install both in 2 steps : 1st w/o certs. Next I set up my DNS inside ispc. And finally I implement certs by php -q update. I have one server with web interface = ns1. One w/o = ns2 I run ispc web interface : cert is OK. I install monit, tests both with success with 'monit status' command. I open ports and try to open it in browser. It works well on ns1.domain.tld:2812 But impossible to open ns2.domain.tld:2812. Firefox tells me "impossible to open ns2 with ns1 cert" ! (it's a sum up of the message ) extract of monitrc file on ns2 : " set httpd port 2812 and SSL ENABLE PEMFILE /etc/ssl/private/pure-ftpd.pem use address 188.8.131.52 allow 0.0.0.0/0.0.0.0 allow admin:moFanfan12Pit " I am thinking, I will have same concern with pure-ftd on ns2 as monit is linked with it certs... Any workaround ? Should I have web interface on all servers ?
