SPA can't fetch http provisioning file

[seawolffeng]

when resync from http. it always shows:

SPA303 ec:e1:a9:cb:15:14 -- Resync failed: http_get failed

i can access using web browser. But the phones always got failed.

sometimes it takes couple of hours to make it success. 

does anyone know the possible reasons?

http or https ?

All at all, catch HTTP request as well as server's response. I wish it will help you. Syslog&debug messages (highest debug level) may disclose something valuable as well.

so, where is the provisioning server?  if it's on a different network you might look at

-DNS - is the dns server correct, and a fast server that knows the provisioning server?

-do the phones have the correct default gateway.

syslog or wireshark capture of the provisioning failing should show what's going on.

instructions for logging:

admin --> advanced
Voice --> system  
add the IP address of your log server in the
  debug and
  syslog, (the same address)
  set debug level =3
Save system tab

You don't need it for this case, but to see sip messages in the syslog,

Go into the line1--> sip settings  -->
  sip debug option  to 'full'
save line1 tab
