HH5 Event Log entry "CWMP: session closed due to error: Could not resolve host"

Go to solution

For several days my Home Hub 5 has been losing broadband connection for a few mins 7/8 times per hour. Checking the hub event log it shows the message "CWMP: session closed due to error: Could not resolve host".Connection is lost for bothe wired & wireless.The BT helpdesk suggersted moving cables to different yellow slots on the rear of the hub, to no avail.

Frustratingly, the 4 online chats I've initiated on this issue have been curtailed due to losing the broadband connection............

Any suggestions please?

What's the firmware recently updated?  I would try a factory reset using the recess button on back and holding 20/30sec until lights flash

Thanks for the quick reply.
Not aware of the firmware being updated, but will try the factory reset & see what performance is like thereafter.

I have now had HH5 reset for 12+ hours & the issue has only reoccurred once, so it looks like your tip is a good one - many thanks!

Sorry to be a gloom merchant , but if the fault lies between your HomeHub and bt equipement {not it your Home wiring ]  in the Exchange then the   ''CWMP: session closed due to error: Could not resolve host" and others may keep happening and another one that causes the disconnects '..
'''PPP LCP Send Termination Request [User request]''.
Unfortunately if the disconnects continue the DLM equipement  at the Exchange will reduce  your Ip profile /BRAS to make your connection stable , therefore a slower download speed , try not to disconect/ switch off/restart  your router too often as the DLM will see that as an unstable connection. I assume that you've done the quiet line test , dial 17070 and your teliphone line should be virtually noise free, if not Report a Phone fault , not a Broadband Fault !!!!

...these are some of my understanding of repetative Disconnections  /stuck BRAS which seem impossible to resolve , until something happens at the Exchange !!

Thanks for your feedback - noted.

The quiet line test was fine.

At the time of writing the line has been stable all day.

That ''Tip'' may have corrected something , but it was Not a Solution to the ..

##"CWMP: session closed due to error: Could not resolve host"##

I and many others are still waiting for a reason, and a real ''solution''  for why this keeps happening , and most importantly a way to stop it happening , and how to prevent our Download speeds dropping  !!

I think you are mistaking cause and effect, the CWMP session closed is probably due to a line problem.

Is there any noise on your line when you carry out a quiet line test on 17070
