502 Bad Gateway - nginx after RUM Injection

MarcoCritti — Fri, 24 Mar 2023 10:27:34 GMT

Hello everyone

We rolled out Dynatrace to our Kubernetes Azure Cluster, We have a landingpage which redirects to another page.
However with RUM on for the landiongpage we get now a 502 Bad Gateway message. If I refresh the page the redirection works fine, however in case I remove the dtCookie the redirection doesnt work and I still have the same error message.

My quick solution is to add the website for the landing page and disable RUM.

The redirect is done via https://learn.microsoft.com/en-us/azure/active-directory-b2c/b2clogin (Set redirect URLs to b2clogin.com for Azure Active Directory B2C)

Any Ideas what could be the issue?

Thanks and cheers
Marco

Hi Marco,
to be honest, I don't know what is the issue exactly, but you can add a custom injection rule from the app settings to prevent the injection for this URL.

and for XHR you can add an XHR exclusion rule.
