Guys, I've been running a relay since many months without issue (Tor 0.2.6.9 on CentOS 6 fully patched) Since a few weeks, my OR port is no longer reachable without apparent reason (Dirport remains reachable on port 9030) [warn] Your server (xx.xx.xx.xx:9001) has not managed to confirm that its ORPort is reachable. Please check your firewalls, ports, address, /etc/hosts file, etc. Nothing changed on my network nor on the config... Both Dir & OR port are open and routed properly (Nmap checked from the Net) Selinux & firewalling are disabled, nothing but localhost in /etc/hosts... I'm kinda puzzled... Could you tell me where I should investigate further? Thanks!
