Windows 10: Windows Update error 0x8024401c and 0x800705b4

Question
-
Hi All,
I'm having problems with Windows Update on many Windows 10 clients (build 1511 and 1607).
All clients are connected on an internal WSUS server on Windows Server 2012 R2.
Many clients works fine and regularly gets updates from WSUS, but on an half of them, I get this error if I check for updates:
"There were some problems installing updates, but we'll try again later. If you keep seeing this and want to search the web or contact support for information, this may help: (0x8024401c)"
or
"There were some problems installing updates, but we'll try again later. If you keep seeing this and want to search the web or contact support for information, this may help: (0x800705b4)"
I have followed all suggested steps available at this URL:
https://support.microsoft.com/en-us/help/10164/fix-windows-update-errors
1) I have executed the "Windows Update troubleshooter"
2) I have manually installed the most recent update KB
3) I have executed "DISM.exe /Online /Cleanup-image /Restorehealth" and "sfc /scannow"
4) I have manually upgraded the build from 1511 to 1607
Nothing changed.
So, I have tried changing my GPO to point to Microsoft servers instead of my WSUS, and if I do this, the Windows Update client getting errors, starts to work.
On some clients, If I run the PowerShell command "Get-WindowsUpdateLog", I can see this log:2017/05/16 13:53:23.6876262 928 376 WebServices Current service auth scheme=0. 2017/05/16 13:53:23.6876277 928 376 WebServices Current Proxy auth scheme=0. 2017/05/16 13:53:25.7027586 928 376 WebServices Auto proxy settings for this web service call. 2017/05/16 13:54:27.6879485 928 376 WebServices WS error: There was an error communicating with the endpoint at 'https://servername.domain.ext:443/ClientWebService/client.asmx'. 2017/05/16 13:54:27.6879507 928 376 WebServices WS error: There was an error receiving the HTTP reply. 2017/05/16 13:54:27.6879522 928 376 WebServices WS error: The operation did not complete within the time allotted. 2017/05/16 13:54:27.6879544 928 376 WebServices WS error: There was an error communicating with the endpoint at 'https://servername.domain.ext:443/ClientWebService/client.asmx'. 2017/05/16 13:54:27.6879562 928 376 WebServices WS error: There was an error receiving the HTTP reply. 2017/05/16 13:54:27.6879577 928 376 WebServices WS error: The operation did not complete within the time allotted. 2017/05/16 13:54:27.6879599 928 376 WebServices WS error: There was an error communicating with the endpoint at 'https://servername.domain.ext:443/ClientWebService/client.asmx'. 2017/05/16 13:54:27.6879613 928 376 WebServices WS error: There was an error receiving the HTTP reply. 2017/05/16 13:54:27.6879632 928 376 WebServices WS error: The operation did not complete within the time allotted. 2017/05/16 13:54:27.6879646 928 376 WebServices WS error: The operation timed out 2017/05/16 13:54:27.6879672 928 376 WebServices Web service call failed with hr = 8024401c. 2017/05/16 13:54:27.6879687 928 376 WebServices Current service auth scheme=0. 2017/05/16 13:54:27.6879698 928 376 WebServices Current Proxy auth scheme=0. 2017/05/16 13:54:27.6879786 928 376 ProtocolTalker PTError: 0x8024401c 2017/05/16 13:54:27.6879797 928 376 ProtocolTalker SyncUpdates_WithRecovery failed. 0x8024401c 2017/05/16 13:54:27.6880057 928 376 ProtocolTalker SyncUpdates round trips: 3 2017/05/16 13:54:27.6880174 928 376 ProtocolTalker Sync of Updates 0x8024401c 2017/05/16 13:54:27.6880636 928 376 ProtocolTalker SyncServerUpdatesInternal failed 0x8024401c 1601/01/01 01:00:00.0000000 928 376 Unknown( 230): GUID=8ce98bfa-21f0-385f-839a-1073774029ac (No Format Information found). 1601/01/01 01:00:00.0000000 928 376 Unknown( 240): GUID=8ce98bfa-21f0-385f-839a-1073774029ac (No Format Information found). 1601/01/01 01:00:00.0000000 928 376 Unknown( 241): GUID=8ce98bfa-21f0-385f-839a-1073774029ac (No Format Information found). 2017/05/16 13:54:27.7654360 928 3608 ComApi *RESUMED* Search ClientId = UpdateOrchestrator 2017/05/16 13:54:27.7660270 928 3608 ComApi Updates found = 0 2017/05/16 13:54:27.7660284 928 3608 ComApi Exit code = 0x00000000, Result code = 0x8024401C 2017/05/16 13:54:27.7660299 928 3608 ComApi * END * Search ClientId = UpdateOrchestrator 2017/05/16 13:54:27.7666645 928 4120 ComApi ISusInternal:: DisconnectCall failed, hr=8024000C
I have also tried to stop the AntiVirus, but nothing changed.
Do you have any suggestion?

I found a way to fix this error.
I have upgraded the affected machines to Windows 10 build 1703, then I ran the "Windows Update troubleshooting tool" and all was fixed.- Marked as answer by thenewmessiah Tuesday, May 30, 2017 3:49 PM

Same here. At first I thought it was a local problem. In my stupidity I put back an image from a couple,of days ago on my work system. Didn't bring any solution. In fact it got worse, because it desperately tried to get updates for,as well Windows 10 as well as apps. Which failed with a boatload of errors as a result. MS is obviously not capable in generating normal errors like 'sorry the update server is down, try again later'. If I would have seen such a message I would not be in the shit I am now. :-(Tuesday, May 16, 2017 6:29 PM

To me this seems like a problem reaching your WSUS server (or the proxy?)
Is this really the name of your WSUS server? "https://servername.domain.ext"

"servername.domain.ext" is a placeholder, not the real address
Also, there is no proxy configured and no firewall between the client and the server.
I can open the address "https://servername.domain.ext:443/ClientWebService/client.asmx" from the affected machines.Wednesday, May 17, 2017 7:48 AM -
Hi,
As I know, Windows server 2012 R2 using port 8531 by default, but I noticed you are using port 443.
Have you changed the port manually?
“So, I have tried changing my GPO to point to Microsoft servers instead of my WSUS, and if I do this, the Windows Update client getting errors, starts to work.”
Do you mean updating from Microsoft server will work well?
Please enter the alternative server address follow the article below:
It is recommend to ask for help from WUSU support as they have more resources to help you.

Hi there. :)
I know this is an old thread now but I had the same problem too. Sometimes Windows update worked and others not.
One day I realised that the updates were always failing when I was using my wired connection. I switched to wireless and Windows update worked. I kept on changing from wifi to wired and testing the updates to check if it was always like that and it was. It only seems to work properly when I used my WiFi. I have no idea why it only works with a WiFi connection. It's weird. :) (Typical Windows).
Maybe it may be the same for you..
Hope this helps.
Best regards. :)

Mine's the opposite. WiFi doesn't work.
A different problem suggested a network reset to fix discovery. I wonder if this is somehow related as the network components used are the same.
....The update troubleshooter found a few errors the install has started again.
Why doesn't Microsoft bake this into the updater? Especially for us insiders running preview builds.

I was running into the same problem - have switched from wireless to wired and the problem was instantly solved. Now I have the latest updates downloaded and installed.

I have the same problem here. On about 55 tablets installed in 2 laptop trolleys, as soon as I switch from a wireless connection to a wired connection, the Windows Updates begin to install. By cons, for me, this is not a solution because I can not connect these 55 tablets on the wired network. The Windows Update should always be installed with the wireless connection. Do you have another permanent solution for me?
