DNS address could not be found. Diagnosing the problem.
What steps have you taken to resolve the issue?
Issue Summary:
Consistent DNS issues when accessing ‘launchlemonade.app’ and ‘seojobs.com’ on initial load and at random times during the day. Encountering DNS probe errors daily on different attempts.
owner of seojobs.com told me they’re set up on Fastly
It appears that launchlemonade.app dynamically assigns different Ipv4s upon multiple nslookup runs.(84.32.84.105, 84.32.84.112, 147.79.119.24, 147.79.119.242, 193.58.105.228, 84.32.84.254)
Details:
Internet Connection: Hrvatski Telekom (HT) with router configured for DNS over TLS (DoT) using Cloudflare’s 1.1.1.1 and 1.0.0.1 servers. The nearest Cloudflare node is ZAG (Zagreb).
Symptom: First cold load of the day for both domains results in a DNS probe error. After reloading a couple of times, they work fine (but happens again later in the day). This issue is unique to these two domains; all other domains load quickly and without issue.
Current Ping Test Results:
ping launchlemonade.app fails with the message: Ping request could not find host launchlemonade.app. Please check the name and try again.
Question:
Is this issue related to my ISP, Cloudflare’s DNS service, or possibly the hosting configuration of these specific domains? Any guidance on how to resolve this would be appreciated.
Thank you,

What are the steps to reproduce the issue?
access ‘launchlemonade.app’ and ‘seojobs.com’ on initial load in the morning when i turn on the PC (we receive a new IP every morning)
mate, same story for me this morning, just launched launchlemonade.app and again the DNS PROBE
something’s really not right here. then after a few moments it works. It’s some DNS settings somewhere, but i really can’t figure out where, if it’s on HT, cloudflare or the domain’s settings, maybe they have misconfigured their dynamic DNS.
my website is hosted in the UK, and i personally set it up via cloudflare and works perfect all the time.
I am using ipv4 as HT connects you only on Ipv4 however i have Ipv6 support also enabled on the Fritz’s side but main is ipv4
Added to the router DNS or rather endpoint device like desktop PC, notebook, etc.?
Looking at peering at CIX.hr, HT doesn’t have it with Cloudflare, meaning you’re going a bit around via different route (not sure if that would have an impact here):
Settings added straight to the router in the Fritz’s settings. Nah the ipv6 doesn’t make any difference but might give slightly better connectivity. It must be something else.
Everything else perfectly works, it’s just these 2 websites which are of some people i know and one i work with, it’s my AI partner. That’s so bizarre man.
I had a look at that provider of yours, they have a 5gbit internet on optics, and so cheap 30€ a month. Suppose only in Zagreb? We get only HT optics here where we are at.
I’ve already let HT know with a technical ticket about this, i am waiting since 23.09.2024, they’ve been incredibly slow to answer, unbelievable this time. Very poor. This is a business line also not consumer btw.
But if it’s on DT, then forget it.
Normally their waiting time on tech enquiries was 1 week which was acceptable-ish, maybe particularly complex this one hummmm
