SMB 1575 ERR_EMPTY_RESPONSE

[Moudar]

Hi

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:

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

or 

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?

[the_rock]

I believe thats default port for smb web UI?

[Chris_Atkinson]

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

[the_rock]

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

Andy

[the_rock]

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

Andy

[Moudar]

adding 4434 works fine.

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

[the_rock]

Glad you got it working!
