Source tree returns 403 Forbidden

[Sriram Vaitheeswaran]

Any git command from source tree ends up with error from April mid 2020.

It just says

FATAL ERROR: Proxy error: 403 Forbidden
fatal: Could not read from remote repository.

Please make sure you have the correct access rights
and the repository exists.

But the sourcetree Terminal and windows cmd executes the same git command smoothly.

I'm behind my corporate proxy. But it was working till mid April as I have already set my proxy in sourcetree application > Tools > Options > network tab.

I'm using gitlab repo. I have authenticated using SSH. I have imported the private key .ppk file in ssh client configuration under Tools > Options > General Tab.

I'm using sourcetree version 3.3.8 in Windows 10 Pro

Issue is fixed by changing the ssh client as OpenSSH as I was having the key at C:\Users\<username>\.ssh\id_rsa
