Autoupdate haven't been working since 20.12.2019

Hello,

our Autoupdate from https://www.insys-icom.de:443/data/autoupdate/mrx/list.txt doesn’t work anymore. This happenend after the 19th to the 20th of december since there haven’ been any other tests.

If we send an user-agent then there is a success but if we cant send an user-agent with us then there is the error code 403 (Forbidden).

What did cloudflare change in the christmas vacation?

What can we do to fix the problem?

Thanks

Greetings

Chris
