I have been running Reposado and Margarita on High Sierra for about 3 years over http without any issues with over 200 clients ranging from 10.6.8 to 10.13.6.

To prepare for Mojave, I have updated the config, catalogs and client url to point to https. I use a prod and test branch and have been able to successfully serve updates to High Sierra clients over https using either the default catalog or the prod and test branch.

Mojave on the other hand has proven a little problematic. I can get Mojave to work when using the default catalogue

defaults write /Library/Preferences/com.apple.SoftwareUpdate CatalogURL https://sasmac01:8090/content/catalogs/others/index-10.14-10.13-10.12-10.11-10.10-10.9-mountainlion-lion-snowleopard-leopard.merged-1.sucatalog

However my issue is when trying to use a branch it reports the following error NSURLErrorDomain error -1100

I have added the SUDisableEVCheck setting as below onto the client

defaults write /Library/Preferences/com.apple.SoftwareUpdate SUDisableEVCheck -bool YES

And created completely new branches but this has me stumped. I can see the branch catalog in a browser

https://sasmac01:8090/content/catalogs/others/index-10.14-10.13-10.12-10.11-10.10-10.9-mountainlion-lion-snowleopard-leopard.merged-1_prod.sucatalog
Or
https://sasmac01:8090/content/catalogs/others/index-10.14-10.13-10.12-10.11-10.10-10.9-mountainlion-lion-snowleopard-leopard.merged-1_testmoj.sucatalog

so I know it is at least published but to no avail. I have also tried a repo_sync --recheck still with no luck.

Any help would be greatly appreciated

We were seeing something similar

Turns out we'd accidentally regressed a change we'd made to fix a similar problem. See greg's post below

https://groups.google.com/forum/#!topic/reposado/qUZBN0Ow8J4

There is a 041-59915 and a 041-59915::1 so in our case following the workaround fixed the issue.

hope this helps

Cheers

Thanks Matt, it worked a treat and kudos to Greg Neagle for posting the workaround.
