HAProxy Down with HTTP site [ 503 Service Unavailable ]

wesleylc1 · Nov 8, 2018, 2:14 PM

Hello everyone.
My "pfsense 2.4.4-RELEASE", has "haproxy-1.8.14", with two frontend for ports "80 and 443", until yesterday both were running, but now only the frontend of port 443 is UP, below some images .
Can anyone give any suggestions on what I can do?

Seems the webserver is slow to respond? (it takes more than 1 second.)

Do you think the problem may be without backend?

Restart the web server.
Now it looks like it's online

Yes it looks 'up' but with a health check time 
of above 900ms its not ideal.
And might go down if load slightly increases.
Perhaps a different 'status' page to check would be better 
than the default '/' url? Or the webserver still has issues?

Piter, hint to fix this problem?

Or if the webserver has issues, fix them .. How? that depends on the issue ..

Pieter, how can I set up a different status page?
