ERR_EMPTY_RESPONSE admin interface

tjcooks4829 · Jan 26, 2018, 3:58 PM

But only on one machine. Any machine on the network can access the admin app, except the one I use all day. Very convenient.

Most of the ERR_EMPTY_RESPONSE conversations I see here relate to Squid – not running Squid
I don't have a weird IP address or anything like that
DHCP scope does not include the pfSense address
I've cleared every cache, tried numerous browsers, same result

Has anyone else faced & solved this? Thanks so much for any ideas.

Cheers,
TJ

What packages do you have installed?

Edit: Quite a few sites recommend the following series of commands to get past this error:

ipconfig /release
ipconfig /all
ipconfig /flushdns
ipconfig /renew
netsh int ip set dns
netsh winsock reset

Just Darkstat. I can access that just fine, now that I look.

I use all the other services provided by the appliance – NTP, DNS, DHCP, etc.

I am one rev behind, on 2.3.4-RELEASE-p1 (amd64) but I believe this issue pre-dates that at least a couple updates.

I've been here for a few years and I don't recall this being a regular problem. The fact that it's localized to one specific system tells me it isn't a generic pfSense issue. Can I assume that you've already tried the commands I listed and they didn't work for you?

I did just complete all those commands (and am pretty sure I tried that in the past). No change.

Agree it's probably not a widespread pfSense bug. Odd that it's just one machine, I can't find evidence of anyone else having the issue, and every other type of connection to that box works fine – it's our DNS server, NTP, DHCP, etc. all that, I SSH into it okay, access Darkstat okay... Network serves a hundred plus users just fine.

I'm solving it by VNC-ing into a machine that I have installed in the server rack. Mildly inconvenint, but works.

Thanks for helping, any other ideas welcome.

I don't know if this will help or not but I had similar issues recently with several pfsense firewalls I have deployed. It ended up being my Bitdefender antivirus on my laptop that was "protecting" me and causing the web gui to come back with the empty response. I have to either disable the protection now or add all the sites/ips to the safe list to access the firewalls. Looking for a new A/V software program now too…
