Hello there,
I am facing SSL certificate issue. I created a sub-domain & configured in stape.io but when I hit preview button on server container GTM, getts following error.
You can always contact Stape support with such a problem:
https://help.stape.io/hc/en-us/requests/new
But it looks like you’re not using the domain you added on Stape? It looks like your added domain is https://server.iconicc.com and there is no problem with it
