I am currently working on Mendix in a Proxy environment.However, when I try to Commit/Pull, it fails with the following error. LibGit2Sharp.LibGit2SharpException: failed to receive response: The server returned an invalid or unrecognized response(無効または認識されない応答をサーバーが返しました) at LibGit2Sharp.Core.Ensure.HandleError(Int32 result) in /_/LibGit2Sharp/Core/Ensure.cs:line 154 at LibGit2Sharp.Core.Proxy.git_remote_fetch(RemoteHandle remote, IEnumerable`1 refSpecs, GitFetchOptions fetchOptions, String logMessage) in /_/LibGit2Sharp/Core/Proxy.cs:line 2306 at LibGit2Sharp.Commands.Fetch(Repository repository, String remote, IEnumerable`1 refspecs, FetchOptions options, String logMessage, ProxyOptions proxy) in /_/LibGit2Sharp/Commands/Fetch.cs:line 81 at LibGit2Sharp.Network.Fetch(String url, IEnumerable`1 refspecs, FetchOptions options, String logMessage, ProxyOptions proxy) in /_/LibGit2Sharp/Network.cs:line 213 at LibGit2Sharp.Network.Fetch(String url, IEnumerable`1 refspecs, FetchOptions options, ProxyOptions proxy) in /_/LibGit2Sharp/Network.cs:line 181 at Mendix.Modeler.VersionControl.Actions.Git.Requests.Fetch.GitFetchLibGitRequest.ExecuteRequest() in Mendix.Modeler.VersionControl\Actions\Git\Requests\Fetch\GitFetchLibGitRequest.cs:line 55 I found a similar problem in the following forum, but I still can't solve it.
