They are on the Birmingham system, I say they as I have a few VMs, none of which allow me to upload, one of them is called “strep-seq”. Upload gets to 1 or 2% and then terminates with an error message “Failed: Upload request failed. (0)”.
A post on another forum suggests that this behaviour is a result of the upload form sending a message to the server and that message is not acknowledged, possibly due to an old version of Galaxy server installation?
Do you need any additional info? What would happen if I were to change the region?
