Thank you for posting that!
You file format looks good! This means the error must be in the file location:
Qiime2 has been told to import the file named 14_1_S53_R1_001.fastq.gz
in the directory from which you are running this import command, but it can't find that file in that directory. Maybe this file was not uploaded successfully to Galaxy, or maybe it's in a different folder?
