Dear Tang,
We can't accept this short description and reproduce your problem!

Could you please provide additional details on the issue? Such as logs, configuration JSON, and the health check status of the downstream service, etc.?

Additionally, you may pose questions in the Discussions space.

[RainySeason673]

This is an obvious and simple bug, and I have tried to print some logs for your reference.

[RainySeason673]

downstream service status is normal, success open by Url , when i comment "ExceptionsAllowedBeforeBreaking" or "TimeoutValue",everything will be OK

downstream service status is normal, success open by Url , when i comment "ExceptionsAllowedBeforeBreaking" or "TimeoutValue",everything will be OK

try to add "DurationOfBreak": yourValue in QoS Section

If the route works well without enabled QoS, then why are you writing us and reporting the issue?
Read the docs → QoS

If you have more questions then post them to Q-&-A discussions❗

As a team, we don't see any issues with Ocelot. There is misconfiguration issue of your ocelot.json

@RaynaldM It can be a bug...

1. use follow two configuration items together:

"QoSOptions": {
        "ExceptionsAllowedBeforeBreaking": 3, 
        "TimeoutValue": 3000 
      }

So, possibly absence of DurationOfBreak can generate an exception. But I wonder if there is no default value for DurationOfBreak.

It seems we have to investigate this case...

actually, I have already configured this item, but the problem is not with it

My configurations are all from official documents , so why do you think there is misconfiguration of my ocelot.json? and why not confirm if this issue exists？

    }
  ],

  "GlobalConfiguration": {
    "RequestIdKey": "ot-traceid"

}

this is my ocelot.json

[raman-m]

Define Catch All route for /user and /order paths and forget about the issue:

"UpstreamPathTemplate": "/order/{catchAll}",
"DownstreamPathTemplate": "/{catchAll}",

and

"UpstreamPathTemplate": "/user/{catchAll}",
"DownstreamPathTemplate": "/{catchAll}",

Also you need define all possible HTTP verbs.

Better to define Catch All for profile paths too:

"UpstreamPathTemplate": "/profile/{all}",
"DownstreamPathTemplate": "/profile/{all}",

Hope it helps!
