Michael Osipov reopened HTTPASYNC-164:
--------------------------------------
> ParseException: Invalid protocol version when using proxy settings
> ------------------------------------------------------------------
>
> Key: HTTPASYNC-164
> URL: https://issues.apache.org/jira/browse/HTTPASYNC-164
> Project: HttpComponents HttpAsyncClient
> Issue Type: Bug
> Reporter: Carlos
> Priority: Major
> Fix For: HttpClient 5.0
>
>
> Hi,
> We have upgraded our Apache HTTP Client library from version 4.1.4 to 5.0.3.
> We are using the async API. Overall, it's working very good. The reason for
> the upgrade is the need of using the new retry feature. However, we have an
> endpoint that requires accessing through a proxy. The problem with this one
> is that it's returning the following error:
> {code:java}
> org.apache.hc.core5.http.ParseException: Invalid protocol version; error at
> offset 0:
> <[0x2e][0x2f][0x30][0x31][0x32][0x33][0x34][0x35][0x36][0x37][0x38][0x39][0x3a][0x3b][0x3c][0x3d][0x3e]>

> Is there a way to solve this issue? Any way to restore the previous version
> configuration?
