Q: Caching Server does not cache its own Installs from App Store

I haven't figured out why my password won't let me into Server in Safe Mode - maybe because the Server Users are part of a Windows Active Directory for the Domain. My normal iMac login is in there as Admin, so I don't know why that won't work, nor work when I changed the Server password. I will look further into this part later.

Anyway, I can log in to the computer in Safe Mode and access the /Library/Server/Caching/Logs and found this in the debug.log after going into the App Store and getting/installing an app:

So in Safe Mode the bolded request worked this time. Will now log in normally and see if the download was cached, and also post the cache log in the Server app.

Sorry about the loss of formatting - not sure why that happened.

Given this part pasted below worked in Safe Mode but not in Normal Mode, is there anything I should disable that could be causing this?

I uninstalled Avira a few days ago, but that didn't seem to help. I also turned off the iMac's Firewall at one point, to no avail as well.

However, even in Safe Mode, the download from the App Store was not cached.

Safe Mode:

2016-06-23 12:22:44.023 Request for configuration from http://suconfig.apple.com/resource/registration/v1/config.plist succeeded

Normal Mode:

2016-06-23 12:53:31.062 Request for configuration from http://suconfig.apple.com/resource/registration/v1/config.plist failed: The Internet connection appears to be offline.

Or is this the time to get into the Unix Shell Script you posted? Would I activate it during the boot up which is when the Server Caching is presumably loaded - or during a Get/Install from the App Store (which is not caching in either Safe or Normal Mode) or ???

Many thanks.

Here is the output from your UNIX shell script.

Thank you for the advice.

Dr. Cleaner and App Cleaner were only installed as tests for the Caching Server - to see if they actually would be cached. I used them mainly because they both come from the App Store, are small in size, and are free - and were giving very good ratings. The problem with the Caching Server definitely existed prior to even installing those two apps from the App Store..

I have not installed any third party software on this computer since installing El Capitan - except for last night when I installed Git from sourceforge.net, thinking at first this was necessary, until I realized there was a Guest way to post the test results.

Do you think it may be the Wacom software that is causing the problems with the Caching Server? It seems very unlikely to me, but I am unfamiliar with how Macs work. I can try and remove that as I don't use the Wacom tablet - it was for another user of this computer in the past.

So there is no good app for removing software, it sounds like. Thank you for this info and what I might be able to do to rectify this.

I can also revert back to Lion, remove various apps that I inherited with this machine, and re-install El Capitan and Server, if that is best. I prefer not doing that, but can if needs be.

Was there anything else about the report that sounds suspicious in terms of disallowing the Caching Server from working properly?

Wacom had an uninstaller so I ran that and Wacom is now gone. After rebooting, I downloaded an app from the Store but it still did not cache. The Caching Log says the same things as previously reported:

Request for configuration from http://suconfig.apple.com/resource/registration/v1/config.plist failed: The Internet connection appears to be offline.

Same for the request for blacklist.

Before doing step one, I checked the Caching Log and found this:

After rebooting later, I got the usual fails:

It is odd that Caching worked above for the RAW Camera Update and says it was via a Get request by "Software Update". I don't have the Advanced section of the Server app for Software Updates turned ON so this must be a different Software Update service that also gets cached?

Rebooting after doing Step 1 and moving the Server from the Trash to Applications, Caching still did not work from the App Store.

Here is the current Caching Log after doing Step 1 altogether.  (Again, I am in Fiji, one day ahead of the US and 5 hours behind the West coast.)

Interesting that the Request for blacklist does not appear here.

Regarding Step 2, it seems I should be able to just reinstall the OS via the Recover mode, right?

I started the reinstall process, but it sounds like the process is going to download the OS via the Internet. I cannot do that here as it is 6.2GB and our bandwidth is very limited. I installed El Capitan via a boot drive and was assuming this process would just use a recovery area on my local hard drive to reinstall from - NOT the internet.

Is the request to "Sign in to download from the App Store" simply to verify the machine or will it start downloading El Capitan again? I will keep it paused here until I find out. It sounds like it should recover from my hard drive but the language of the request is misleading. Please let me know. Thank you.

I decided to continue but it allowed me to cancel when it got to the part about downloading additional components that would take 197 hours. lol

So this is not an option. However, I can restore back via the Time Capsule to just after installing El Capitan to 10.11.3 via a USB drive and the additional upgrade to 10.11.5 - if you think that would help.

This backup would just be a few weeks ago so I am not sure what could have gotten screwed up within that short period of time. Also, I have already installed the Server App twice via download and also as you instructed yesterday - to no avail. Plus Safe Mode had the same issues.

It is odd that I have gotten some iOS devices' downloads cached but not the server's own downloads. I wonder if the Apple Store works from here but not the App Store in terms of caching? I will try that.
