Domain cannot be resolved/pinged for some internet providers

Hi community,

my domain flightsearch.app is registered via GoDaddy and points to Cloudflare Nameservers. Since yesterday many users report issues to connect to the website. This affects two major internet providers in Austria: A1 and Drei.

Ping is negative, while other customers can access with no issues.

Any advice? Is this an ISP problem? But would be a coincidence if two different providers are affected at the same time.

Thank you for any help!
Best,
Toan

Your issue could be related to:

Even though the thread title suggests this only happens in Leipzig/Germany.
There are already 2 reports of similar issues in Vienna/Austria.

Do you have proxy mode enabled for your website?

Yes, proxy mode is on. I will try without. Thanks a lot for the hint. Seems to be exactly the same issue.
