Issue with uploading fastd data to Raw Sequencing Data Upload


I have a problem when I try to upload my fastq.gz data. I can select the data but I don’t see any progress of the upload. I don’t have much experience with this.
The files are named as follows: REI-23_S6_L001_R2.fastq.gz
I think they are too “big” as they are 9-20 MB each, but I don’t know how to compress them further as the original data is 60-80 MB.
I have tried uploading in Firefox and Edge.

Maybe you have some idea what is wrong.

Thanks for your help
