FMC - custom network feed asks for md5 URL

[hash2k2]

Hi,

I want to add a custom network feed on my FMC. It runs with 7.1.0

The documentation and text field in FMC says "optional", but if I try to add something the field turns red and does not let me add the URL.

Attached to screenshots.

Anyone an idea?

I was able to resolve this myself in a way. If you set the refresh rate of your list to 1 hour or more, then the MD5 checksum is now longer required.
