Error 404 when refresh data/form view

Why is my erpnext (v15.27.6) throwing error 404 after I refresh the browser in form view, data view, and print view with saved data? I tried it on another server also with older erpnext (v14.8) but it works fine.

Share the screenshot and share the error from the console log and paste it here. because everything is working fine. No problems were encountered in the latest versions 14 and 15.

Thanks for your response, this is my access log from apache2
