mount.nfs:portmap 查询失败:RPC:无法接收 - Centos 7 客户端拒绝连接

我正在尝试连接到 nfs 服务器。我看到了以下问题。

mount.nfs: timeout set for Mon May 11 19:27:01 2020
mount.nfs: trying text-based options 'nfsvers=3,addr=IP'
mount.nfs: prog 100003, trying vers=3, prot=6
mount.nfs: portmap query retrying: RPC: Timed out
mount.nfs: prog 100003, trying vers=3, prot=17
mount.nfs: portmap query failed: RPC: Unable to receive - Connection refused
  1. nfs-utils 已安装并在客户端中运行。
  2. rpcbind 正在客户端机器上运行
  3. 端口111、2049和892向NFS服务器开放。

但我不确定我是否遗漏了解决此问题的任何内容。
