We are currently moving some reactive Spring Boot application to Microsoft Azure (Container Apps). Since moving those applications to the Azure network we see sporadic DNS resolution issues and opened https://github.com/netty/netty/issues/13660 to find the reason for that.
One comment suggested to enable TCP fallback for DNS resolution. Now I'm trying to find out where to find the default configuration for the resolver (spring, reactor?) and if this has enabled the TCP fallback or not. Can anyone point the location where this is set up?
Thank you
