I am receiving a Http Status 500 - NullIamSorry error when trying to add a billing server in UCM - 6.1.3a. Has anybody seen this before? Rebooted the machine - still no luck.
HTTP Status 500 - nullI am sorry
type Status report
message nullI am sorry
description The server encountered an internal error (nullI am sorry) that prevented it from fulfilling this request.
I assume you modified the credentials on the host that is configured to receive the CDR files. Can you test access to the billing server from a non-CUCM box (like your PC/laptop?). If the server is setup for SFTP, use putty or something similar to test from the non-CUCM system. Also (if using SFTP), you could test basic connectivity from the CUCM system by using a file get:
admin:file get tftp Ringlist.xml
Follow the prompts and push the file to your CDR billing server (using the same credentials, storage path, etc.). Ensure that you can download the file successfully.
Check the user ID that you are using to ensure that you don't have something flagged like "User must change credentials on next logon.".
Also, if you are using SFTP: has anything changed on the SFTP server recently? Such as changing/adding a banner page? I had issues on 6.1 systems when backing up files to a SFTP server and it was directly related to the banner page.
I apologize for being all over the place with this but it appears that your issue with the HTTP Status error is more symptomatic than causal. Particularly when this started cropping up after you tried to change credentials. Sounds like an error condition is hit and the page that CUCM would normally load to communicate error is causing your HTTP status issue. But I am just speculating at this point.
Check the above and let us know what you find.
