Config ReRoutes use DownstreamHostAndPorts can success,but use ServiceName throw exception.

I guess this is more of a Consul health check definition problem, not Ocelot related.

HTTP checks also support TLS. By default, a valid TLS certificate is expected. Certificate verification can be turned off by setting the tls_skip_verify field to true in the check definition.

https://www.consul.io/docs/agent/checks.html

[jonny-xhl]

I try setting tls_skip_verify field to true,but also throw the exception

[jonny-xhl]

@yuft ,Can you tell me Consul health check definetion where is problem.
The show check success.

[yuft]

Just saw you had "UseServiceDiscovery": false, maybe you can remove it and see if it makes any difference.

Just saw you had "UseServiceDiscovery": false, maybe you can remove it and see if it makes any difference.

Now,I setting sigle Consul server can success.
Don't change Ocelot config.

@jonny-xhl
I believe PRs #1670, #1377 should resolve your problem. If Not then it seems it's Consul configuration issue.
Let me know testing results please!
