Can’t renew LetsEncrypt cert on a FreePBX system. Posting here in the hopes that y’all will have some valuable feedback.
Ran a packet capture whilst requesting the cert. It gets all the way to the acme challenge from remote servers. My server sends back a 200 OK.
Then I see a BUNCH of SYNs from the same servers that my server never respond to. The remote servers keep retransmitting the SYNs, but after awhile, seeing that I’m not responding, they give up.
I’m very confused. Can’t run certbot manually in the terminal and can’t find LE logs anywhere T_T. Not sure were to go from here
