I have three Windows Server 2012 R2 that are CM clients that for the last few months have failed to download and install updates. When I go to Software Center, there's a list of half a dozen updates that have failed, all with error code 800705B4. Also, there are two applications that haven't installed; they are stuck at status downloading 0%.
The odd thing is that these are CM Dist Points, and I have confirmed that the content has gone out, both from the distribution graph being 100% all green, and the fact that the other servers have installed the updates successfully.
In the logs, I see CAS failed to download update (guid). Error = 0x800705b4. Releasing content request.
What would cause these systems to hang on downloading updates and applications?
Hi SeekellRoger-1704,
Thanks for your information.
According to my research, Error 0x800705b4 means “this operation returned because the timeout period expired”. However, to better understand the issue, could you please collect CAS .log, Locationservices.log and Updatedeployment .log?
Besides, for error 0x800705b4, maybe you can try the method in the article.

Good morning, and thank you for your response. How do you want me to get these log files to you? And what time frame do you want to see?
@Seekell, Roger Thank you for your reply! Did you find anything in the logs?
Good morning, @chunhuaizhangMSFT-8922 . I don't understand. You said, "Could you please collect CAS .log, Locationservices.log and Updatedeployment .log?"
What do you want me to do with them exactly?
Thanks in advance.
Hi @Seekell, Roger ,
For further analysis, we want to know if there are error messages from these logs.
For example: (Just for your reference.)
1) Locationservices.log: Records the client activity for locating management points, software update points, and distribution points.
Is the communication between the DP and the client normal? Are there any errors reported?
2) Updatesdeployment.log: Provides information about the deployment on the client, including software update activation, evaluation, and enforcement. Verbose logging shows additional information about the interaction with the client user interface.
What step is the update?
3) CAS.log: Provides information about the process of downloading software updates to the local cache and cache management.
Thanks for your time and patience.
I have submitted a Microsoft support request. Thank you.
Hi , did you get a answer to the issue you had
Good morning. It was a cert issue; we use HTTPS / certs in our env. (Take the following as-is with no warranty)
TLDR: check IIS for expired certificate on the client
1. Open IIS (inetmgr), go to Default Web Site, edit bindings > HTTPS
2. View the cert; if it is expired, select a different cert
3. Open command prompt: iisreset
4. Restart ccmexec service
Also ensure client can talk to DP over 443 (check firewall, boundaries, etc.)
