I saw the following question, but the thread was locked without any answers. I am having this same issue; what is the solution?
Hyperlinks from brands and store emails including newsletters that contain “ctrk.klclick.com” are failing to load in any browser — this has just started happening for me. I’m running iOS 26.6 on my iPad. How can I find out why this is happening and is there a fix I can implement?

Hyperlinks are reliant upon DNS services to resolve a human-readable URL to an IP Address. DNS services may intentionally block (or "sink hole") IP Addresses that host inappropriate or malicious content, or are known to have been compromised. Many ISPs also use their DNS service to filter age-appropriate material.
If only some websites or URLs are blocked for sites that you wish to visit, you might consider manually changing your DNS server settings - although you need to consider that known-bad sites and services might also be blocked by other DNS providers.
I suggest using one of the following DNS services - for which IPv4 and IPv6 server addresses are listed:
Quad9 (highly recommended)
9.9.9.9
149.112.112.112
2620:fe::fe
2620:fe::9
OpenDNS
208.67.222.222
208.67.220.220
2620:119:35::35
2620:119:53::53
Cloudflare
1.1.1.1
1.0.0.1
2606:4700:4700::1111
2606:4700:4700::1001
If you need to reconfigure the DNS settings for your iPad (or iPhone), these are set individually for each WiFi network that you connect to:
Settings > WiFi > [Your WiFi Network] - tap the blue "i" icon - [DNS] Configure DNS - select Manual
For redundancy, enter all four of the DNS Server entries for the chosen DNS service, one per line, exactly as shown. The sequence doesn't particularly matter; delete any other DNS Server addresses before selecting Done.
If you are unsure how to change your DNS settings, or are uncomfortable doing so, a really easy way to set and manage them is to use a third-party utility App - DNSecure:
https://apps.apple.com/app/dnsecure/id1533413232
DNSecure also usefully enables secure DNS capabilities (using DoT or DoH) for your device.

Have you tried to restart the iPad to see if the issues persist?

Using a different DNS service provider is simply a choice...
Instead of using your ISP's default DNS server, you are simply choosing to use a different DNS provider. This costs nothing. Changing DNS provider may bypass any content filtering or parental controls offered by your ISP (if any).
Thank you for this detailed reply. This happens on my iPad and iPhone (both iOS 26.6) but does not happen on my iMac (OS Sequoia 15.7.7) I cannot upgrade any further due to the age of my iMac. I will consider the reconfiguration.
Is there any downside to doing this?
Yes, many times, and I've performed a complete power down.
Thanks!
You're very welcome.
