Subdomain stopped working overnight – wrong IP not resolving

Website URL

https://pop-grafika.xo.je/

Error Message

ERR_CONNECTION_TIMED_OUT (initially) After debugging with curl: curl -I -v http://pop-grafika.xo.je HTTP/1.1 403 Forbidden X-SPS-Security-Policy-Result: business-sec

Other Information

dig pop-grafika.xo.je +short

Output:

167.206.37.145

But in the control panel, it should point to:

185.27.134.55

When I try to connect:

curl -I -v http://pop-grafika.xo.je

Output:

HTTP/1.1 403 Forbidden
X-SPS-Security-Policy-Result: business-sec

This looks like a completely different server (possibly ISP/security filtering), not InfinityFree.

What I’ve already tested

• Tried different networks (WiFi + mobile data)

• Used dig and curl for debugging

• Confirmed account is active in panel

• Verified correct IP in control panel

Questions

1. Why is my xo.je domain resolving to a completely different IP (167.206.37.145)?

2. Is this a DNS backend issue or something wrong with my account configuration?

Additional note

I’m currently on the free plan , and I was actually considering upgrading to premium. However, this issue is a bit concerning since both domains stopped working suddenly without any changes on my side.

Is this something that can happen on free hosting, or should I expect more stability on premium?

Any help would be appreciated — thank you!
