I'm trying to get Connected Cache (DOINC) to work on our 1906 environment, but the installation of the service will not finish according to distmgr.log.
As far as I can tell from DoincSetup.log, it stops at requesting the test GIF file from the internet.
("requesting content from the delivery imitation in-network cache (DOINC) instance.")
This environment requires the use of a proxy server, for accessing the internet.
It does not require authentication, just that the traffic goes through the proxy.
I have tried adding (and verifying) the proxy in IE in System context using Psexec.exe -i -s, but no change.
I have tried adding the proxy in web.config (defaultProxy) on the CacheNodeService (and Default website) website in IE, but this doesn't seem to help. Also the information is removed again, every time DOINC setup runs again, so it seems like a loop at the moment.
How can I specify a web proxy for DOINC to use?

Please refer to the following URL for SCCM site system server proxy settings.

Actually a friend (thanks Phil!) reached out to the product group came back with a fairly simple workaround, until they get it fixed.
In IIS manager, expand the Server Farms and expand each of the list farms.
Under "Servers" use the "Add Server" function and add your proxy server and take the original server offline.
It's a bit tricky to get it installed, as the installation itself assumes it can perform a selfcheck during installation.
Watch the log file (SMS_DP$\Ms.Dsp.Do.Inc.Setup\DoincSetup.log) and IIS manager and once the b1.download.windowsupdate.com Server Farm is created, do the Add Server/Take offline switch there.
Do the same for the tlu.dl.delivery.mp.microsoft.com Server Farm.
Once that was done, installation selfcheck worked and the service got installed.
And everything seems to be working now, through the proxy without any changes to the proxy config.
I have a feeling this will be fixed, in one of the next SCCM builds.
I have tested it with a number of Office 365 ProPlus versions, including changing from 32 to 64 bit and back again and installing Visio/Project only with getting data through MCC.
So far we haven't seen any issues.

I have been wondering the same - I haven't tried the latest SCCM TPs, to see if it was fixed there.
But it would maybe make sense, if during provisioning of the MMC service, grabbed the configured proxy on the site server and configured that, the same way as we do.
And update/remove if the proxy configuration changes.

@Axel Laudan For the record, this is listed in the What's new in version 2002 of Configuration Manager current branch article:
If your environment uses an unauthenticated proxy server for internet access, now when you enable a Configuration Manager distribution point for Microsoft Connected Cache, it can communicate through the proxy. For more information, see Microsoft Connected Cache.
