Hi, the ip address of our mails erver looks to be blocked, ip address: 51.222.173.52, this is a recently adquired ip address from our dedicated server provider, in a new zimbra installation, thanks in advance
Please fill out the fields below so we can help you better. Note: you must provide your domain name to get help. Domain names for issued certificates are all made public in Certificate Transparency logs (e.g. crt.sh | example.com), so withholding your domain name here does not increase secrecy, but only makes it harder for us to provide help.
is exactly the same software installed on both, i supsect maybe was something with the ip address of the first one: 51.222.173.52 but now i am figuring out there is one diference on the network configuration, the first one --> 51.222.173.52 traffic pass through an aditional router (without NAT, only routed) and the server have two ip address, i don't know if maybe these is the problem the second one is connected directly. What do you recomend i can configure the first server without the aditional router to check if the problem persist
Thank you for your help, now i was able to generate the certificate
