Error trying to use behind an authenticated proxy server

[josuemb]

When I try to use it behind a proxy server I get an error (trace below).

I am configuring proxy with:

cosmosDBConfig.getConnectionPolicy().proxy("127.0.0.1", 808);

However I am not able to find any way to configure proxy usr/pwd even when netty support this scenario.

R:/127.0.0.1:808] The connection observed an error

@josuemb which spring-data-comosdb version are you using ?

[josuemb]

Ver 2.2-.1

[kushagraThapar]

Did you try using ConnectionMode.Gateway while creating connection policy ?

[josuemb]

It works, it just limited since you need to capture user/password in each execution. Do you know any other option. We have an environment when at development time all user should access by proxy.

[kushagraThapar]

@josuemb - do you still need to support username/password scenario in proxy environment ?

[josuemb]

You can proceed to close this. Thank you.
