Multiple Question in orthanc server

Is there a possibility to have our custom DNS for DICOM server?
I am getting Error during store while sending to modality , How to resolve this?
I am not able to write any query?

1. I think there shouldn't be a problem adding a DICOM node to a DNS server. But that's not something I have attempted.
2. Have you set up the AETitles, IPs and ports for the modality and Orthanc? What's the error message? What's written in your configuration.json?
3. Are you querying through Orthanc Explorer? Or writing your own HTTP POST request?

i have setup AETtile ip and port no. i am getting this kind of error in the log

I'll be honest and tell you I don't really understand the log so much, so just want to confirm:

Are you trying to store something from Orthanc (where you copied the configuration.json from) to another Orthanc (Renga)?
