Sometimes, when working on an Acquia Cloud project, I seemingly spontaneously lose git access on the AC server. This might be related to switching between multiple workstations while working on the project. When I try to run a git command, I get

Permission denied (publickey). fatal: Could not read from remote repository.

I have not changed my keys related to this project.

I haven't determined the root cause of this issue, but I found a functional solution:

When I get this issue, rather than in my IDE I ssh to AC via the Acquia Dev Desktop interface (clicking the small terminal icon next to the SSH address). This runs a specific SSH connection with several options:

ssh -p 22 -i "/Users/username/.ssh/acquia_key_name" -o StrictHostKeyChecking=no -o UserKnownHostsFile=/dev/null [email protected]

After this command is run (in my case in Mac Terminal), I can access the git repo again via my IDE.

I was having a similar issue with connecting to Acquia Cloud within my vagrant box. After reading the above solution I managed to get the connection to work by running the following from my home directory:

ssh -p 22 -i ".ssh/acquia_key_name" [email protected]

Then I ssh-ed back into my vagrant box and managed to connect
