Screenshot

Expected behavior Git Sync is setup sucessfully

Desktop (please complete the following information):

• OS: Windows 10 10.0.17763
• Installation Method: installer
• App Version: 2021.4.1 and 2021.5.0-alpha.2

Additional context We're using a selfhosted GitLab and the connection to gitlab from my client is through a SSL-Terminating proxy. Normal git-operations using git-cli, git-fork or visual studio code are successful. My local git installation is configured to use this proxy and the proxy is configured in Insomnia aswell (HTTP-Requests using Insomnia work).

Hi @higgs01, thank you for reporting this!

We will need to investigate this further, but are you by any chance still able to reproduce this using latest Insomnia release?
