I started the JetBrains Gateway and want to connect to my coder workspace. The workspace is located behind an Azure AppProxy, so the Authorization-Header has to be set. This is accomplished by the use of the header-command.

When I try to connect, a new session token is requested, I authorize against AAD and retrieve the token. Then the Gateway want to retrieve the coder-binary and this fails with an error:

` CLI exited unexpectedly with 2.

I tried to debug the problem by using the mitmproxy and got the following screenshot:

The first two requests have the Authorization-Header set (not shown here) - but the requests to get the coder-binary lacks the header. This seems to be the cause for my problem, but I may be wrong. Has anyone been able to connect to a coder workspace behind an AppProxy?
