Hello, I was wondering, have any of you set up Server Side Tagging in Google Tag Manager?
I am receiving a geolocation issue here. First I used the Google’s App Engine domain.
Through this setup, I received the following information in my HTTP requests with correct values:
But now, since I linked my own sub domain to run everything in first party context, the values of these data aren’t right anymore. For some reason the X-Appengine-User-Ip uses the second value of X-Forwarded-For (and not the first anymore).
Any tips on how I can fix this? I already tried the ip_override option, but Google doesn’t allow this at this point.
