Application failed to connect to Nacos server: "nacos.super.bifchain:8848"

As an AI language model, I do not have access to your application or the Nacos server. However, this error message suggests that your application is not able to establish a connection with the specified Nacos server at the given address and port.

There could be several reasons for this, such as:

1. The Nacos server is down or not accessible from your network.
2. The address or port number is incorrect or has been changed.
3. There could be firewall or network restrictions that are preventing the connection.

To troubleshoot this issue, you can try the following steps:

1. Check if the Nacos server is up and running.
2. Verify if the address and port number are correct.
3. Check if there are any firewall or network restrictions that are blocking the connection.
4. Ensure that your application has the necessary permissions to access the Nacos server.

If the issue persists, you can seek help from your application developer or Nacos server administrator for further assistance.

seate java.lang.IllegalArgumentException: A.grouplist is required在配置了seata: registry: nacos: server-addr: 127.0.0.1:8848 namespace: "" application: seata-server group: DEFAULT_GROUP username: nacos password: nacos tx-service-group: seata-demo service: vgroup-mapping: seata-demo: A

这个错误是由于配置文件中的 `seate` 配置项中缺少了 `grouplist` 参数引起的。`grouplist` 参数用于指定 Seata 服务的注册中心地址，以及注册的分组信息。

你可以尝试在配置文件中添加 `grouplist` 参数，例如：

seate:
  registry:
    nacos:
      server-addr: 127.0.0.1:8848
      namespace: ""
      application: seata-server
      group: DEFAULT_GROUP
      username: nacos
      password: nacos
    grouplist: 127.0.0.1:8091,127.0.0.1:8092
  tx-service-group: seata-demo
  service:
    vgroup-mapping:
      seata-demo: A

这里的 `grouplist` 参数指定了 Seata 服务注册中心的地址列表，多个地址之间使用逗号分隔。

如果你已经正确配置了 `grouplist` 参数，但仍然出现该错误，请确保 Seata 服务已经正确启动并且可以正常连接到注册中心。同时，也要检查网络连接是否正常，确保能够访问到指定的注册中心地址。
