Server workflow results stuck loading

[devonsimms]

When I got to my workflow results page it says my workflow was successfully run, but when I click it to access the results and download the outputs it gets stuck on the loading page and I cannot see the results. This is a large workflow I run weekly. I have had this problem before but usually when I rerun it it works the next time. i have now run it 4 times with the same issue. Please advise
