Hello kblin！ When I use the following statement to download：

ncbi-genome-download -g delete1.txt bacteria -F fasta the following problems arise： Download from NCBI failed: ConnectionError(MaxRetryError("HTTPSConnectionPool(host='ftp.ncbi.nlm.nih.gov', port=443): Max retries exceeded with url: /genomes/all/GCF/002/177/455/GCF_002177455.1_ASM217745v1/md5checksums.txt (Caused by NewConnectionError('<urllib3.connection.VerifiedHTTPSConnection object at 0x7f7fce0c8ba8>: Failed to establish a new connection: [Errno -2] Name or service not known'))"))

Hello, have you solve this problem?

There seems to be a number of same issues describing this exact problem on the issues page. For future reference, if you're seeing the same message it almost exclusively means there's a network problem, and not ncbi-genome-download issue.

The problem could be:

  1. Your computer's network policy is wonky - are you behind a firewall by any chance? Some school networks prohibit connection to outside FTP from some weird reason.
  2. NCBI is down for maintenance - while they tend to have excellent uptime for what they are/do, the service does go down occasionally for maintenance. You can check for current status here: https://www.ncbi.nlm.nih.gov/down/

In my case, I'm seeing the same message and have confirmed NCBI ftp servers are offline today for maintenance and update.

Hope this helps!
