Watchdog shows that Apache is down, while it is actually running on a server:
# status httpd status* running
The following is written to
CONFIG_TEXT: 'apache' trying to restart'apache' stop: /usr/local/psa/admin/bin/websrvmng'apache' start: /usr/local/psa/admin/bin/websrvmng'apache' failed, cannot open a connection to INET[203.0.113.2:80]
Unable to telnet to the server IP-address on 80 port:
# telnet 203.0.113.2 80Trying 203.0.113.2...telnet: connect to address 203.0.113.2: Connection refused
Server IP got banned by Fail2Ban, that is why Watchdog cannot retrieve Apache status at 80 port.
Add the server IP-address to the list of Trusted IPs of Fail2Ban in Tools and Settings > IP Address Banning (Fail2Ban) > Trusted IP Addresses
