I have my deployment server settings set for SFTP and being authenticated using SSH key pair with saved passphrase.
This works perfectly in 2021.2.3. selecting the "Deployment->Sync with Deployed To..." option connects to the remote server and allows me to manage my updates nicely.
After installing the 2021.3 update I can't get PhpStorm to connect to the remote server without needing me to enter the login password. The previous settings all look correct so I have no idea why they're not working. Rolling back to 2021.2.3 the settings work again.
I know there were changes to deployment in 2021.3 but wouldn't expect that to break my SSH configuration.
