After installing Portainer according to the official documentation and running the ./update.sh script, I can no longer ping port 80. During the update, I did choose to enable Docker native IPv6 as suggested.
I am not sure if either one of these changes is causing my issue since I am just now noticing it, but that’s all I have changed recently. I noticed it in my ACME logs that my certs were not being renewed.
Checked my firewall, port 80 is open (also temporarily disabled the firewall to troubleshoot)
netstat -tulpn | grep LISTEN | grep :80
tcp 0 0 127.0.0.1:80 0.0.0.0:* LISTEN 28281/docker-proxy
telnet (my server) 80
Trying (my IPv6 address)…
Connection failed: Connection refused
Trying (my IP address)…
telnet: Unable to connect to remote host: Connection refused
All other ports seem to be working fine. Can anyone offer any possible insight to my problem? Thanks in advance
