$SSH_AUTH_SOCK has an incorrect value
I've been dealing with random hangs when using git, more so using git pull for some reason, after checking the $SSH_AUTH_SOCK variable it was set back to /private/tmp/com.apple.launchd.xxxxxxxx/Listeners, had to manually unset the variable so that it changed the value to ~/.1password/agent.sock and that fixes the issue.
I'm using Fish as my shell if that matters, but this is something that I frequently have to fix, and it's my only annoyance with the SSH agent.
