when I switched back from same origin custom domaindomen.com/metrics to Subdomain setupss.domen.com
the problem is gone
That’s why I think that the problem is in cloudflare (the setting was 1 in 1 according to stape instructions)
Yes, it looks like you are passing in ip_override always the IP address of the Cloudflare server.
Check in incoming requests to sGTM in preview, what ip address do you have in the headers of the incoming request, in ‘X-Forwarded-For’? Is your real IP address there?
