@creaton60 have you tried to set the maxIdleTime property?

spring:
    gateway:
      httpclient:
        pool:
          max-idle-time: <PUT_YOUR_VALUE_HERE>ms

AFAIR by default, it is NULL so your connection will be waiting forever without closing it on the gateway and it may be closed on server site.
