Unable to copy multiple files via scp - ssh

Question

This command for connecting to my aws server works well:
ssh -i my_pem.pem ubuntu#ec2-xx-xx-xx-xx.eu-west-1.compute.amazonaws.com
But this not:
$ scp -v -i my_pem.pem file1 file2 ubuntu#ec2-xx-xx-xx-xx.eu-west-1.compute.amazonaws.com:/home/ubuntu/folder1
UPDATE1:
$ ssh -v -i 123.pem ubuntu#xx-xx-xx-xx.xx-west-1.compute.amazonaws.com

What's the matter?

Answer 1

See the difference
debug1: Connecting to xx-xx-xx-xx.xx-west-1.compute.amazonaws.com [11.22.33.44] port 22.
and
Executing: program /usr/bin/ssh host ip-xx-xx-xx-xx, user ubuntu, command scp -v -d -t /home/ubuntu/folder1
ssh: Could not resolve hostname ip-xx-xx-xx-xx: Name or service not known
Your scp is connecting somewhere else and since you obfuscated the IPs/addresses I have no idea if that is intention or that the it really does.
The scp is parsing your files and probably found some : character in your file name (first guess about # was false) and parses that filename as host:path? Give it a try with only one of the files, post the real name of files.
Or rather use sftp. It does not care about the syntax on command line. Just sftp your host and then:
cd folder1
put my_file file2
