Deleting form: 502 bad gateway

Hello

I am trying to delete a form but I keep receiving an error message

“Unable to delete asset”
“502 bad gateway”

image

username - xxxxxxx
form - “Seroprevalence survey”

I have downloaded the data and the form. From looking through the community this seems to happen if there are REST services on the form but I don’t have any for this form.

Any help would be much appreciated.

Thanks,
Dave
