From the second screenshot it seems the POST request goes to com.snowplowanalytics.com/tp2, which is not the default path the Snowplow GTM SS Client claims requests to. The default path is /com.snowplowanalytics.snowplow/tp2, exactly as you also mention.
You can still set another custom POST path in the client configuration if you wanted to.
hey @Ada, thanks, that was the issue! I assumed the default path is com.snowplowanalytics.com/tp2 but in the template for some reason its com.snowplowanalytics.snowplow/tp2 good catch, now it does work as expected.
I do have 1 side issue with container responding 404 for whatever reason, but that’s likely to be the issue how I deployed it.
