aaPanel_Kern vumanhcuong02 Hello, your server may have its own web service, and it occupies port 80. Use the command to check what program is occupying port 80 netstat -tulnp|grep 80
aaPanel_Kern brian The server network connection to the ssl provider timed out. It is recommended to check whether the network is normal? ping acme-v02.api.letsencrypt.org -c 5 curl -v https://acme-v02.api.letsencrypt.org
aaPanel_Kern brian The connection timed out, it is recommended to use a third-party SSL. Or consult the server provider that the network cannot be connected
brian aaPanel_Kern I tried to use third-party ssl. but it needs CSR request. how can i generate that?
brian aaPanel_Kern Would you be able to check the panel when you have some free time? I am unable to do anything, neither install nor update any modules
aaPanel_Kern brian Hello, is it okay to try to delete the bound node and try again? Where is your server located? It is recommended to consult the server provider network problem sed -i "/aapanel.com/d" /etc/hosts
