Luminita, we would need more information on what is happening. Can you look at any logs that may at the same time arise in the browser console? We'll try to share more steps on how to collect more informations as well.

Hello Alexandre,
I did not encounter this issue lately, but I will keep in mind to try to capture any logs, if possible.
Could this have been related to the issue with the VPN integration code, which also brought the VPN integration icon in FxE instead of the Access Connector one?
Thank you.

The issue might be related to the Built-in VPN setting in FxE, which is checked and locked.

Got some clarification on this prompt from the VPN team, and this error prompt is specific to a failure to refresh the auth token for the VPN auth provider. We have replaced the IPPFxaAuthProvider we were leveraging for AccessConnector with a custom IPPEnterpriseAuthProvider purpose-built for our use case. It's worth monitoring this to see if that change has resolved whatever caused this intermittent error prompt.

This prompt will also be getting phased out in favor of an error page based on bug 2033526, so it may not be worth changing in our fork unless it becomes more prevalent.

Is it worth augmenting logging so that it can be surfaced via e.g. MOZ_LOG and thus the profiler, for easier long-running diagnosis?
