Unable to reach Vaultwarden server from users MacOS - Failed to Fetch

[JDI01]

Hello, running into an issue where the DNS is resolving but something is blocking traffic to the vaultwardens server ip address. User cannot log into Bitwarden client.

First, the issue was that the users password no longer worked, prompting for Invalid Master Password. I recovered the account in the admin console and tried to log in on the users MacBook. It says failed to fetch.

Failed to Fetch occurs using the chrome extension of bitwarden and the desktop client. Unable to ping server from terminal. Unable to visit web gui.

I am able to log in on my desktop using the users bitwarden credentials just fine. Unable to do anything from her Mac.

I checked System Settings → Privacy & Security → Local Network and also checked the firewall. Nothing about Bitwarden there.

Update: flushing the dns and resetting the network resolved the issue.
