When configuring an indescribable service on the ucloud international version machine today, we encountered the error of socket.error: [errno 99] cannot assign requested address. The details are as follows:

socket.error: [Errno 99] Cannot assign requested address

Originally thought it was the problem of resolver, but it was still unsolved when Google’s nameservers were specified, so I thought it might be the problem of server IP address setting, because Alibaba cloud defaulted to bind the intranet IP address to the network card.

Then modify the server IP in the configuration file of a service to, and then start the service. The problem is solved.

Remember to release the used port (generally 8001) in the security group.
