Extremely High Ping Rates on Spectrum (3000-5000ms)

We’ve setup spectrum for our Minecraft server, however, when we connect to the server through the spectrum domain we get extremely high ping rates (2000-5000ms)

We’re based in Turkey and Cloudflare claims that it has 2 datacenters in Turkey, so what is the reason for this high ping rates? and how can we fix it?

Did you recently setup spectrum or have you been using it for a while? What is the affected domain?

Are you using Argo Smart Routing? If you disable it, solves the problem?

I’ve just bought spectrum, the domain is mc.aesirmc.com

No I am not using Argo.
