Hello Guys,

I have installed SCOM 2019 fresh and patched with UR2. Unfortunately after i tried to download Management packs from the catalog it's not working and also Updates and Recommendations is not working. I get the following error :

Operations Manager cannot connect to the Web Service
" The Microsoft Management Pack catalog Web Service cannot be contacted at this time. There is either a problem with your internet connection or the web service is offline."

my troubleshooting so far :

  1. I have tried starting the SCOM 2019 UR2 Console from another PC - my workstation- I see the Same issue.
  2. I have found old solution for SCOM 2012 to edit the SCOM Console config file and add the proxy option - It didn't work.
  3. I have tested opening web sites from browser and it works fine. Even the microsoft catalog website opens from IE.
  4. I Know that the company only allows TLS 1.2

IS TLS related to this issue ? How can I solve this problem ? Any suggestions ?

    Hi @D D ,

    just to make sure I got this right - your management servers can connect to Internet, but still you get the error?

    I see you already did some research, wanted to ask you if you came across this one and if you tried all the suggestions from the different users?

    • Ops Console Proxy Settings

    Use Proxy Settings in Operations Console

    • Check in your browser if the web page is accessible:

    https://www.microsoft.com/mpdownload/ManagementPackCatalogWebService.asmx

    • Try using ProcMon to trace where the requests go and then make sure those IPs are allowed through your corporate firewall:

    SCOM 2012: Operations Manager cannot connect to the Web service
    http://systemcenter.no/?p=292

    • Try to reset the IE settings:

    It is also always a good idea to sit down with someone from the network team and check in the firewall logs if the communication from the management servers is blocked.

    Please let us know what happened!

    Hello Stoyan,

    Yes you got it correct. The management server can connect to the internet.

    The browser can access the internet and no proxy setting is really needed. We don't use proxy. Also the management pack page https://www.microsoft.com/mpdownload/ManagementPackCatalogWebService.asmxis accessible through the IE browser.

    What ports do I need to get this working ? I already have 443 and 80 ? I see there is firewall enabled on the box. Is it possible to block something ?
    What is the TLS protocol that is being used by SCOM ? I have only TLS 1.2 the older one are disabled because unsafe.

    THanks
