Built-in Firefox VPN stopped working after updating to Firefox 158.0.1

Firefox VPN

Hello,

The built-in VPN in Firefox was working correctly before the update to version 158.0.1. After updating, it stopped connecting and displays this error: “Couldn't connect to VPN. Try again in a few minutes.” The same error occurs in a private window. Troubleshooting already performed: DNS over HTTPS is off. Remote improvements are enabled. browser.ipProtection.enabled is set to true. network.proxy.type is set to 5. about:policies reports that the Enterprise Policies service is inactive.

Could this be a regression in Firefox 158.0.1? Please advise how to restore the built-in VPN. Thank you.

Hi

What happens when you have those prefs set to their defaults?

Thanks for your reply. Could you please specify which preferences you mean? I haven't intentionally changed any preferences in `about:config`; I only checked the values of `browser.ipProtection.enabled` and `network.proxy.type` while troubleshooting the VPN issue.

merci bien

@gabriela.jati, did changing those prefs back to default fix your issue?

Hi there Thanks for your kind message. Thing is I hadn't changed anything before I couldn't use the vpn any longer... it just stopped working. I reported the issue to bugzilla and I'm waiting for a reply before trying to change anything... which I'll probably do soon.
