    Hi D_Lav ,

    I am wondering if the issue is in DNS policies - perhaps the you do not have a public DNS resolver?  Are you allowing all the possible domains - they should be *.powerbi.com, *.analysis.windows.net or *. servicebus.windows.net.

    OR, do you have some sort of antivirus software that is blocking it?  Either by domain or endpoints?

    Is there a log being built that maybe gives a hint?  That should be at: C:\Users\<GatewayServiceAccount>\AppData\Local\Microsoft\On-premises data gateway\GatewayConfiguratorLogs

    OR, you could just run a network trace with something like Fiddler to see where the block might be occuring.

    i think its solved! FOR some reason, DNS was able to resolve all endpoints except api.powerbi.com. So Powerbi.com could be resolved which was weird. It seemed to be on server side so what we (Security person and i) eventually did was to update C:\Windows\System32\drivers\etc - Hosts file with the following, 

     api.powerbi.com
     api.privatelink.analysis.windows.net

     

    After this it worked.

I have checked an all ports etc are open so everything according to communication should be correct? We dont allow names with wildcards so i guess that Azure service tags should take care of that? the list is updated automatically when a new list is published. 

 

i did find a funny thing regarding another gateway in my cluster (to which i want to connect the new gateway that im trying to install). On my main cluster instance, proxy is configured. Its not configured on the second member or on the new one that i am trying to configure/install. 

 

Problem is that, as soon as i try to remove it. gateway stops working. This is a production machine with hundreds of datasources connected to it so i am deadly afraid of trying to destroy anything so my business need to redo all datasources. 

 

Could this have anything to do with the issue on the other servers? The idea of adding a new member to the cluster was because i eventually wanted to reinstall the main member to remove the proxy. OR if anyone else has a better option i am all ears around that.
