I cannot connect subdomain

You created a subdomain and installed WordPress there also? That’s not how you are supposed to work with WordPress networks.

You create the subdomain on your webhost cpanel, and point the subdomain to the same place as your main domain.

Then in the WordPress Network Admin, you create a new site with the subdomain as the complete address.

Then you should have the main domain and the subdomain in the same network install. After that, Broadcast should work automatically.

ok. if a begin again with a new sudomain, is there a link with help with this: “You create the subdomain on your webhost cpanel, and point the subdomain to the same place as your main domain.”??? thank you

It depends what control panel your webhost has. You’ll have to contact them for more information on how to create a subdomain.

Here is some information regarding how to install a network: https://www.ads-software.com/support/article/create-a-network/

If you have any further questions just write.

i have done all that ok? afteer that what i have to do? i have got plesk. i create a new subdomain test.gogosgrouplaw.gr .. what i have to do now???

I am not familiar with Plesk.

Perhaps search or ask in the networking forum? https://www.ads-software.com/support/forum/multisite/

thank you very much. i appreciate yur help.

I usually run the other direction when I see Plesk…

That’s often a good indicator of a Windows-based server

I received

The site you were looking for, https://test.gogosgrouplaw.gr/, does not exist, but you can create it now!

So your wildcard DNS seems to be working but the multisite doesn’t know about your subsite.

I also found a website at https://thegreeklawyer.gogosgrouplaw.gr/ which looks like a fine website but I can’t tell if that’s on the multisite or not.
