DNS SRV record present but version is still fetched from main domain

[soupdiver]

I have setup a SRV DNS record but when testing my domain federationtester reports 404. I checked the JSON log and can see that the record was detected properly but federationtester still tries to fetch the version from the main domain? Is this expected or am I holding it wrong?

I thought the whole point of delegation is to delegate everything to the subdomain. I also checked https://github.com/matrix-org/synapse/blob/master/docs/delegate.md#delegation-faq but couldn't find something specific to my issue.

log:

sounds like a dup of #99 ?

Fixed it by using .well-know Seem I did not understand how that SRV record is supposed to work
