HTTPS Post Bad Request

Greetings all.

My application works with a remote server. Server uses https
authorization of the certificate. I have following code to authorize and
sends request:

uri = URI.parse("")
http =, '443')
http.use_ssl = true
http.verify_mode = OpenSSL::SSL::VERIFY_PEER
http.ca_file = File.join(File.dirname("public/certificate.pem"),
http.start do |http|
      req ="/cgi-bin/expr/export.get_pay_systems?partner_id=1003")
      responce = http.request(req)
      resp = responce.body

this code works well, I get the data from the server. BUT when I try to
make POST request:

http.start do |http|
      req ="/cgi-bin/expr/payment_transactions.verify_order",
      responce = http.request(req)
      resp = responce.body

I get an error from the server:

Your browser sent a request that this server could not understand.
Request header field is missing ':' separator.

what is that be? I tried to find a solution, but to no avail. the
Internet caught the message that it could be antivirus, but I'm on
Linux. I will be glad to any thoughts!
