Can not access Inventory - LMS 4.2.5

[Ralf Boehm]

Hallo,

I have the following prolbem. If I access "Inventory->Add/Import/Manage Devices" I got this error:

"Error in communication with DCR Server. ..."

But the DCR-Server is running.

I have tried something to solve the problem, check some files and the content of these, check hostname. Nothing helps. I have found in the log from CTMJrmServer that the server can not connect to https://<hostname>:443, and so the CTMJrmServer didn't start. But I can not find any reason why.

Logfile:

Also I can not access dcrcli. I got Authentication failed. Is there any relation?

Can anyone help me to solve the problem?

Thank you very much for your efforts

I have the same problem:

Error in communicating with DCR Server. For more details click here.

DCR Server may be down. Please start the DCR Server and then refresh the page.

I can't start the DCR Server:

 DCRServer Administrator has shut down this server 

The BD is OK

No errors reported
INFO: /opt/CSCOpx/databases/cmf/cmf.db validation complete.

I remove all the logs files.

Other errors:

I try to find a solution.

Hello,

so I need LMS everyday (nobody like to see the nothing :-) ), I tried to install a new virtual appliance. If I read the release-notes I found, that is possible to reinstall LMS 4.2.5. I tried it. I clone the appliance and reinstall on the clone without connected to the network (same ipaddress). Everything goes fine and all processes are up after finished. Ok, so I shutdown both aplliances, disconnect the old from network and connect the new to network. Start the new aplliances, same problem. I start the old (without network), all processes are up. :-/

Whatever the reason is, if start the appliance without network-connection, all processes are up. So I delete the new, start the old without network, look on the console that all processes are up. If so, connect the network and all works fine.

Hello Michel,

it seems, that the daemon-manager not run. Which OS you use for LMS?
