I have a problem and I am at the end of my knowledge. I have already read all the threads about it but can not find a solution.
I currently have a Lets Encrypt certificate which will expire soon. But I can not update it because I always get the error.
Self test error: Pest_Curl_Exec - Connection timed out after 5000 milliseconds Does DNS for sub.domain.de resolve correctly? Local DNS result: xxx.xxx.205.109, External DNS result: xxx.xxx.205.109 Processing:sub.domain.de, Local IP: xxx.xxx.205.109, Public IP: xxx.xxx.205.109 Self test: trying http://sub.domain.de/.freepbx-known/ebd7d59be15252d963ef8ffc30bb770e Self test error: Pest_Curl_Exec - Connection timed out after 5000 milliseconds
In pfSense I have already tested everything, I can access the Admin Portal, UCP etc. via the new subdomain, also the address is resolved correctly, because I have entered an A-record at the DNS provider. I have disabled the firewall, disabled responsive firewall, also I tried to update the certmanager via edge but it is up to date (15.0.43). The port for LetsEncrypt is also enabled and in the firewall the responsive LetsEncrypt rules are also enabled. Everything does not work, now I need your help.
