Revolving around the core of technology
Synaman server has an issue with port 80.
When an end user is attempting to access over port 80 they get no response. Port 6060 works as expected.
Additionally when attempting to enroll a certificate I get the following error:
Web server listening on port 80 redirects client's requests to https://ftp.mydomain.com/LPgihqyl.html. You will have to disable this redirection in order for LetsEncrypt's challenge/response to work. Code: 301
Disabling "Force HTTPS" has no effect on either.
I have confirmed that Synaman is the application listening on port 80
Hi,
Try connecting to http://ftp.mydomain.com and confirm you see SynaMan's login page and not some other server on your end. The most common reason for such errors is that your router/firewall is routing traffic for port 80 to a different machine.
