I am trying to provision D785 on freepbx using http. I enter the provisioning url as http://pbx-fqdn/tftproot and in logs I see below messages

Oct 26 04:03:12.935 [DEBUG2] WEBCLIENT: Socket 22 connected

Oct 26 04:03:13.094 [NOTICE] WEBCLIENT: handle_challenge: http server is asking for credentials!

Oct 26 04:03:13.094 [NOTICE] WEBCLIENT: handle_challenge: resending request !

Oct 26 04:03:13.095 [DEBUG2] WEBCLIENT: Send TCP connected

Oct 26 04:03:13.253 [NOTICE] WEBCLIENT: handle_challenge: former http client authorization failed!

Oct 26 04:03:13.253 [NOTICE] WEBCLIENT: handle_challenge: asking user for authorization data !

Please help in below two questions

1> Is the provisioning url is corect

2> as freepbx need credentials for http provisioning, were we can provide the credentials in SNOM phones
