Thank you for providing a detailed bug report. Alas, you are using an unsupported version of Zuul. Zuul 1 (and the integration with Spring) is no longer supported.

can you give me solution for this? which Zuul version should i use and which spring integration ?

carl-mastrangelo commented 4 years ago

@thanhphi0401 sorry to be the bearer of bad news, but Spring only integrated with Zuul 1 which is no longer supported. Zuul 2 was not integrated into Spring, so unfortunately you're in a position of being forced to either move to Spring's own proxy, or live with occasional connection error logs.

@thanhphi0401 sorry to be the bearer of bad news, but Spring only integrated with Zuul 1 which is no longer supported. Zuul 2 was not integrated into Spring, so unfortunately you're in a position of being forced to either move to Spring's own proxy, or live with occasional connection error logs.

but do you know what exactly this error?

I do not. They happen pretty frequently, so I wouldn't be concerned. Connections do break occasionally.
