Hi,

I'm having issues login into CUE
System details:
UC-520
CUEv3.0
CCUME v4.2(0)

Basic error = "Cisco Unity Express has lost contact with the host router"

Attached screen shots may be more helpful

Screenshot1, I'm able to login to cue but it then takes me to screenshot2 where it states that cue has lost contact with the host router" I tried the same user/pass word I used in screenshot1 but no luck

I tried these steps with no success.
Enabling the HTTP Server
Enabling GUI Access for the System Administrator

Any help will be greatly appreciated

It seems that your cue is not started.  What happened before this happened?
Did you update or restore some configurations?

Looks like I'm able to login via CLI but not web (it takes me to screenshot2). Not really sure what's going on. I did see read/write errors with flash. Just recently, I rebooted and was taken to rommon. Boot couldn't open flash and could not determine first file name. I was able to recover from this, but now the phones will not register, and I still can't login to CUE via web interface

Also, I don't see the voice vlan (100) defined in CCA. I only see the default vlan of 192.168.1.1. This may be part of the problem I suppose? I've tried adding this, but doesn't allow me.

The cue relies on the cUe starting, if it can not read/write to the second flash, that might be an issue.  A mismatch between the startup/router config and cue will prevent it from starting.
Do you still have access to cisco support?  Do you have a good back up of the cue?

No Cisco support. Don't think there's a backup of CUE. CUE is started however. See screenshots (cue1.png and cue2.png). My issue appears to only be with cue web access. Does the flash card contain cue web files? If so, I don't see cue related web files on the flash drive. The flash had read/write issues and needed to be reformated and IOS reinstalled. I noticed that it also lost the vlan.dat and needed to recreate it. Phones wouldn't register until I added vlan 100. I don't know if cue web interface is complaining about missing web files, or if cue can't communicate with the router because of issues with vlan 90? Vlan 90 is created but no IP associated with it. If I log into CCA > configure > switching > vlanls, I see default (192.168.1.1), vlan 100 (10.1.1.1), and vlan 90 (no IP info). Like I said, I had to recreate vlan100 and vlan90, but I'm unable to add IP 10.1.10.2 to vlan 90. States that it is being used by local loop.

Your configuration is off.
Usually:
192.168.10.0/24
10.1.1.0/24
10.1.2.1 is the cue IP.
10.1.10.1 is the CUE web interface. VLAN 90

you need to add the IP range and VLAN 90 to the integrated
interface Integrated-Service-Engine0/0
 description cue is initialized with default IMAP group
 ip unnumbered Vlan90
 ip nat inside
 ip virtual-reassembly in
 service-module ip address 10.1.10.1 255.255.255.252
 service-module ip default-gateway 10.1.10.2

Open in new window


Do you have a backup of running/startup config?
It might but when you are going through the web browser, what IP are you connecting to?

I do have a backup of the running config.

10.1.10.1 is the web browser IP I use. I can access this page and login fine, but redirects me to screenshot2.png page "lost contact with router".  I can ping 10.1.10.1 and 10.2.10.2. I can telnet and login to cue with no issue. Just issues with the web interface.

I've added the IP ranged specified above. I think this was part of the issue, but I think I'm still missing something. After adding "ip unnumbered Vlan90 (before it was "ip unnumbered Loopback0"), the login seems to try longer but ultimately fails. It may be due to this error? "You may need to copy the GUI files on the CME flash and enable the HTTP server on the CME router". I don't see GUI files in flash..

Looks like I have a CCA backup that was created 11/15/2013. This backup should be fine since there hasn't been any changes configuration wise since that time. Do the cca backup do a complete system backup (Callmanager, cue, flash)? If it recovers the Items in flash, then I think this may fix my issue.

There are two types of backup one can make using CCA all inclusive and a partial i.e. backup a components separately.

Create a backup with CCA of the current setup.
Then restore the prior and see if that restores your data.
If something goes wrong, you can at least bring the system back to the current environment.

Note that some restore have an adverse impact i.e. tries to bring non exiting references, etc.

The restore fails, but I can see how it attempts to restore files to flash. Unfortunately it fails before it restores the gui files.

Since CUE CLI works, I've learned to use this instead.

Thanks for the assistance.

Wasn't able to restore the gui files. It was to much of a hassle to do this. CUE CLI works fine for me and will my alternate solution
