code=404, data=null #3871
Description
I deployed a service using dynamic routing, where routes are published through the Gateway. However, an intermittent issue occurs: when making requests through the Gateway, I experience sporadic 404 errors. For example, only about half of the requests (like 5 out of 10) succeed, while the rest return 404.
Yet, after restarting the Gateway service, everything works fine.
I’ve configured weights for the services (e.g., one service has weight=100; for two services, the weights sum to 100). My Spring Cloud version is 2021.0.8. What could be causing this problem?
like this:
