Running two VPNs on the same device can definitely cause routing conflicts. One approach might be to use Tailscale's split tunneling or configure only specific traffic to go through PIA while leaving Tailscale traffic outside the VPN. It may also be worth checking whether the exit node is becoming a bottleneck due to encryption overhead or network settings. Hopefully someone who has successfully combined PIA and Tailscale on Unraid can share their configuration.
Thanks for the suggestion. I’ll try booting into Safe Mode first to rule out any plugin or driver conflicts. If that doesn’t help, I’ll proceed with a manual update following the Unraid documentation you linked. I appreciate your help!
