This error appears to indicate that fabio was unable to connect to the local consul agent. Is there a consul agent running locally?

As you can see from the following output, even with registration disabled, fabio will still connect to consul to obtain routes and whatnot:

If you don't wish to use consul as the backend, then you will need to select a different backend using -registry.backend, such as -registry.backend file or -registry.backend static.

[pserranoa]

is not a issue! We found the problem. We have consul with tls at other port, exist any way to present a valid cert to auth to consul with tls

[magiconair]

@i4s-pserrano @snh is correct. That flag only prevents fabio from registering itself in consul as a service but it still uses consul to get the routing table.
