Why terraform can't find my provider plugin?

Terraform
1

Hi, I am new to terraform.

we are using tencent private cloud, and our working environment have no internet access.

my setup:

environment variables:

TF_CLI_CONFIG_FILE=/home/gitlab-runner/tools/terraform/.terraformrc
TF_PLUGIN_CACHE_DIR=/home/gitlab-runner/tools/terraform/providers

/home/gitlab-runner/tools/terraform/.terraformrc:

provider_installation {
  filesystem_mirror {
    path = "/home/gitlab-runner/tools/terraform/providers"
    include = ["registry.terraform.io/*/*"]
  }
}

and the provider cache folder:

[gitlab-runner@VM_160_238_centos test]$ ls -l /home/gitlab-runner/tools/terraform/providers
total 276812

-rwxr-xr-x 1 gitlab-runner gitlab-runner 236703744 Aug 30 21:58 terraform-provider-tencentcloud_v1.81.119

testing files:

provider.tf

terraform {
  required_providers {
    tencentcloud = {
      source = "tencentcloudstack/tencentcloud"
      version = "1.81.119"
    }
  }
}

provider "tencentcloud" {
  region = "ap-guangzhou"
  secret_id = "***"
  secret_key = "***"
}

main.tf:

resource "tencentcloud_cos_bucket" "test-bucket" {
  bucket = "test-bucket"
  acl    = "private"
}

when terraform init:

Initializing provider plugins...
- Finding tencentcloudstack/tencentcloud versions matching "1.81.119"...
╷
│ Error: Failed to query available provider packages

│ Could not retrieve the list of available versions for provider tencentcloudstack/tencentcloud: provider registry.terraform.io/tencentcloudstack/tencentcloud was not found in any of the search locations

what’s wrong with my code ?
