+## TLS troubleshooting: 
+1. If a Let's Encrypt certificate fails with an invalid Order error 400 that's either because the issuer or cet-manager weren't 100 ready while grafana ingress was being deployed
+**Slution**:
+redeploy using terraform replace the ingress resource
+```bash
+$ terraform apply -replace=kubernetes_ingress_v1.grafana[0]
+...
+
+Apply complete! Resources: 1 added, 0 changed, 1 destroyed.
+```
+2. Rate Limit:
+   
+Up to 10000 certificates can be issued per registered domain (i.e we used nip.io) every 7 days. When this limit is reached you need to wait
+```Error
+Failed to create Order: 429 urn:ietf:params:acme:error:rateLimited: too many certificates (10000) already issued for "nip.io"
+```
