Akismet is reporting “We can’t connect to your site. Your firewall may be blocking us. Please contact your host and refer to our guide about firewalls.” This started a couple weeks ago.
When I type sudo ufw status, it says sudo: ufw: command not found.
When I type iptables -L, it says
Chain INPUT (policy ACCEPT)
target prot opt source destination
Chain FORWARD (policy ACCEPT)
target prot opt source destination
Chain OUTPUT (policy ACCEPT)
target prot opt source destination
which I guess means I don’t have any rules. Akismet says in their docs that they need a TCP connection. I don’t know how to give them that. I also don’t know what changed two weeks ago as it was working fine before that.
What else can I check? Is there a way to ping Akismet through TCP to make sure that’s the issue?
