Token update request failed RequestError: connect EACCESS

Hello, we are encountering a connection issue with our Pritunl servers since yesterday (without any changes made to the infrastructure) on Windows devices.

After several device reboots, it seems to be working, but this is not acceptable.

We are receiving the following message:

Profiles: Token update request failed RequestError: Request: Client Error: connect EACCESS ...

Do you have any leads on this issue?

This is a Windows firewall error. It could be a incorrectly configured firewall or anti-virus software modifying the firewall. Connections to localhost should not be blocked.
