I have a fresh openstack deployment (kolla-Ansible). Everything but Heat is working fine.
When I do a webrequest (either horizon or curl) on the openstack heat endpoint (internal or public), I just get nothing and after a while, it times out with a 500 http error.
Hold up, 504 is a gateway timeout (presumably from HAProxy). But this isn't a 504, it's a 500. And it's not clear if it's heat-api or HAProxy that's generating the 500 response.
FWIW, it always pays to set your HAProxy timeout longer than the RPC timeout in heat-api, so that if a message gets dropped you'll see that reported by heat-api rather than HAProxy.

In the heat_api log I see the request coming through, but it seems that there is just no reply. >> 2019-02-15 14:16:40.047 25 DEBUG

This *is* logging a response though - 300 Multiple Choices, 327 bytes in 0.001106s. Which is the correct response for "GET /" (it should return the version negotiation doc).
Should the api give some output when I do a http request?
Generally speaking, yes.
Any hints?
Thanks a lot, its quite urgent..
Built 11.0.0 and current rocky-stable (11.0.0.1dev), same on both versions.

There are indeed no responses logged here.
Have you checked the heat-engine log to see if the cause of the delay appears there? Is heat-engine alive? Is RabbitMQ working?
