gateway error

[developers-youcong]

Describe the bug
SpringCloud Version:Hoxton.SR4
SpringBoot Version:2.2.6.RELEASE
JDK:1.8

The microservice corresponding to the gateway mapping reported an error, and the corresponding microservice was restarted, but it was not the fault of the microservice. The microservice had no obvious error log, but the gateway log found the error.

error log:
