### Question
- What do you want to know?
While using the SkyWalking monitoring service, an error was reported while
calling a third party interface

Trying restemplate, OkHTTP, httpClint is the same case
Attempted to disable SkyWalking monitoring, and the interface resumed
fetching
The interface returns to normal when these monitoring plug-ins are removed
An attempt was made to filter the endpoint using Trace, and the interface
was normal without error
But treating symptoms does not cure the root cause
What is the reason for this?
When I used the same method to call the local interface, everything worked...
