VPS builds WordPress and fails to download/update theme plug-ins

Yesterday, a netizen set up his own Wordpress website in a VPS, but there was a prompt for downloading and updating plug-ins in the background“ An unknown error has occurred. It may be that WordPress.org does not work properly, or the local configuration is incorrect. If the problem persists, please visit the Chinese support forum. "This is the first time that Lao Zuo has seen this problem. He has seen the prompt that the permissions are not enough. We only need to give permissions to the directory to complete it. How can we solve this problem?

When encountering this problem, we must go online to find out if there is a similar problem. The online tutorial is to open the vi/etc/resolv.conf file of our VPS, and then confirm whether our local DNS is normal. It is recommended that you change it to nameserver 8.8.8.8 and nameserver 8.8.4.4

Then the VPS server must be restarted. If there is still no solution (this friend is, there is still no solution), the solution I suggest is to change the space. There is no problem when he changes to another VPS, and there is no need to just change the DNS. Lao Zuo also did not know where the problem was. The same program, the same one click installation package. For different VPS vendors and different IPs, I guess it can only be the latter. Is it a configuration problem or a service provider IP problem?

Are there any friends in this situation?
