Hi Everyone:  
In currently situation, ACS can find my easycwmp, but when i click reflesh button or sommon, there is a Internal server error.

I checked the genieacs-ui, there is a query fault:

And i use the wireshark to check i find that there is a http 401 authentication fail:

It seems that there is not Digest Auth data

I had set the admin-\>config

I don’t know if there is any connection between the two things.  
If you know how to fix that, please let me know.

thank you!
