Hello, I develop blast application and I want to send my query to NCBI server "remote". so, I develop Perl file that send a command to blastn.exe.

The command is:

$ProgramPath\\blastn.exe -task blastn -db \"$databaseName\" -query $dataPath/testinput.txt -remote -out $dataPath/testoutput.out

Where $ProgramPath=path to .exe files $databaseName = refseq_rna $dataPath = path to text files "input - output" Now, I got these error:

Error: (301.23) [CONN_Read(blast4/HTTP)]  Unable to read data: Timeout[30.000000]
Error: (301.23) [CONN_Read(blast4/HTTP)]  Unable to read data: Timeout[30.000000]
Error: NCBI C++ Exception:
    "..\..\..\..\..\src\serial\objistr.cpp", line 518: Error: byte 188696:  Frame type= eFrameClassMember, Member name= total-length ( at Blast4-reply.body.get-databases[])

Error: (303.7) [URL_Connect]  Socket connect to www.ncbi.nlm.nih.gov:80 failed: Closed

Anyone can help me with this please?

There is a problem with your internet connection, maybe you connect to the internet through a proxy.

Check your proxy settings and internet connection.

Since previous posts posted about where the problem likely comes from, here is a post providing at least some direction to resolve the issue: Howto use NCBI programs behind a HTTP proxy

At least, that worked for me after getting the respective information, i.e., the HTTP_PROXY_HOST and HTTP_PROXY_PORT which will depend on your universities/institutes configuration.
