We are seeing this issue in a Nomad cluster with ACLs and Connect jobs (Nomad: 1. When enabled, both tools must be configured so that workloads running in Nomad are allowed to access Vault. If not given then the default token is used for these operations. Use recommended best practices to generate security credentials, create client and server configuration files, configure and start Consul service, bootstrap the ACL system. All Consul and Nomad servers and agents are on the same Tailscale network (not sure if that makes a difference) Nomad does not have CA or encryption keys configured but the CNI plugin is installed on all Nomad clients. When specifying policies by IDs you may use a unique prefix of the UUID as a shortcut for specifying the entire UUID. These include jobs, allocations, deployments, and evaluations.

Consul connect works well and services are able to communicate with each other. If you generate your own certificates, make sure the server certificates include the special name server. This article (How Nomad Manages ACL Tokens/Polices for Consul Service Mesh – HashiCorp Help Center) mentions, that SI tokens, that are generated by Nomad are only generated with a Local scope and are no longer replicated. The below image shows the service running on prod-do-sfo3-s-2vcpu-4gb-amd-nomad-client-b290 and prod-do-sfo3-s-2vcpu-4gb-amd-nomad-client-64a9t0.
