SMB 1575 ERR_EMPTY_RESPONSE

Moudar — Thu, 02 Oct 2025 11:48:14 GMT

I got two devices (1575 Appliance R81.10.10 - Build 993) on two different sites.

When I try to login via GUI, I get (ERR_EMPTY_RESPONSE) on any browser on both

I have tried to find httpd2 service:

# ps auxw | grep httpd2 root 14622 0.0 0.0 4480 844 pts/0 R+ 13:16 0:00 grep httpd2

but looks like the service is not running!

and no service httpd2:

cpwd_admin list APP PID STAT #START START_TIME MON COMMAND RNGD 3172 E 1 [18:27:33] 16/7/2025 N /pfrm2.0/bin/jitterentropy_rngd -v SSHD 6059 E 1 [18:27:42] 16/7/2025 N /pfrm2.0/bin/sshd -f /pfrm2.0/etc/sshd_config -p 22 -D cposd 4368 E 1 [18:27:39] 16/7/2025 N cposd RTDB 4402 E 1 [18:27:39] 16/7/2025 N rtdbd SFWD 12535 E 1 [18:38:59] 16/7/2025 N fw sfwd CVIEWAPIS 17754 E 1 [23:57:43] 1/10/2025 N cpview_api_service CPVIEWD 9903 E 1 [18:28:41] 16/7/2025 N cpviewd

The device is running as usual as firewall and VPN device. but i cannot login to GUI ?!

[Expert@U]# find / -name httpd2 find: /proc/15286: No such file or directory [Expert@U]# which httpd2 [Expert@U]# command -v httpd2 [Expert@U]# ls /web/cpshared/web/Apache/ ls: /web/cpshared/web/Apache/: No such file or directory

So any idea what to do next?

Hey bro,

I did some search on this and points to try below 2 things:

1) /etc/init.d/httpd2 restart

2) check if below exists:

# ls -l /pfrm2.0/httpd2

# ls -l /web/

If all good, then try install latest firmware, but if that fails too, maybe reboot. if still no go, I suggest TAC case.

[Expert@U]# /etc/init.d/httpd2 restart bash: /etc/init.d/httpd2: No such file or directory [Expert@U]# ls -l /pfrm2.0/httpd2 ls: /pfrm2.0/httpd2: No such file or directory [Expert@U]# ls -l /web/ lrwxrwxrwx 1 root root 20 Jul 16 18:27 cgi-bin -> /pfrm2.0/var/tcl_cgi [Expert@U]#

Restarting needs a maintenance window, so it is not an option just now!

I think the fact that directory does not even exist is your issue, just my 2 cents. I would try upgrade to latest firmware, reboot, see what happens. if no dice, would definitely open TAC case.

To confirm you tried https://<IP address>:4434 or a different port?

I believe thats default port for smb web UI?

Correct and if you go to just 443 you will see the err from the original post...

I always keep forgetting that, thanks Chris. @Moudar can you ensure it is connecting on port 4434?

Just for my own sanity, I spun up demo point and I see port is indeed 4434.

adding 4434 works fine.

I wonder what happend! They worked fine before. I mean without adding the 4434
