Hi,
we've blocked http/https to internet on firewall gateway and now we can't update ctr office with configured winhttp and ie proxy settings.
I can see some requests on proxy to f.c2r.ts.cdn.office.net, but a lot of requests go to non-official MS IP ranges (seen on firewall) bypassing the proxy and getting error 30183-27 (2147954552).
Allowing ip ranges on firewall gateway from next site doesn't help:
Some IPs example seen on fw:
104.85.248.75 80
104.85.248.82 80
20.199.120.151 443
