Not sure what is causing this problem but in CCA remove it from the community and add it again, this way it discoverers it from scratch.
This may or may not work and is the first thing I do when this particular problem happens to me.
Check this picture out...
I have TELNET access - web access everything.. CCA is just confused.. I have removed from CCA and readded it. I had CCA 3.0 and upgraded to 3.1 and the same thing happens... This site has been installed and working for 3 years... and this is now happening... I could always use CCA to check settings....
Ok, and when you telnet manually, Do you do it from the same PC? What IP address are you manually telnetting to? I am trying to see if you are telnetting to IOS CUE CME, etc. David may know bwtter, but if the CUE sessions are locked up you may not be able to use CCA to get into the UC.
Make sure you do not have any extra NIC's active or any FTP software running in the background.
John - I would consider myself an expert in UC500 and CME... I have been doing this for many years... This one is weird. I can telnet into the same device in both CME and CUE side.... using the same credentials. I am telling you... CCA is wacky! CUE side is not locked.. I can successfully telnet into it once in CME and there are no active sessions blocking CCA. This happens even after a restart of the UC520 box. Interesting enough that I can telnet into it manually... but it does seem like something is blocking CCA..... But this is not only on one machines.. This happens from any machine that I install CCA on and try.. I have it on a server and my laptop that I use at every site I go to. Good thing I know CLI well.... because I dont need the wizard but I am trying my hardest to follow Cisco's lead.... by using the CCA... but little things like this are really making it hard..
You and I have one thing in common it would seem We have an uncanny ability to find unusual problems and we find them regularly
I am curious though, when you remove it from the community and then restart CCA, then add it back in does it come up with a certificate request?? This certificate window is essential and at times it does not appear for unknown reasons.
Can you also tell me what options are chosen in the Advanced Tab?
(PS) I understand the CLI option you are taking, but if I can help you out to avoid going down that path I would do what I can to see that come through.
