Proxy configuration on Talend ESB

avaras — Sat, 16 Nov 2024 05:59:11 GMT

Hello

We deploy a bundle into Talend ESB and when it tries to connect to a SoapService through a proxy launch an excpetion (502 http error), and i don't know where it is necessary to change configuration to modify nonproxyHosts, because i'm accesing an internal server into the same lan.

What i see is when i make the first request system properties http.proxyHost, proxyPassword, nonProxyHosts are modified.

Error summary

Hello,

Please try to also verify if it works with auth-free proxy (whether the proxy takes effect).

Best regards
