Adsense giving me "Invalid URL" error when submitting website

I've submitted my site to both adsense and infolinks and I get this error. To be clear, I haven't submitted my site and it has been rejected. The forms do not allow me to continue and I just get that error.

I have a discounted namecheap domain so it's not a normal .com or .org ect. It was registered less than 2 weeks ago. It's a wordpress 4.9.7 website. It was originally created on 000webhost, but I soon bought real hosting and made a backup to transfer it. And I'm using the wordfence free version plugin.

I was able to get a response from Infolinks and they said they are looking into the problem. I'm not sure if any of the above info helps, but maybe someone would see a red flag that would be causing the problem on my end.

Any advice would be appreciated. Thanks.

Not normal - you mean it has a different extension, like .kr ?
It doesn't look like technical issue if site is loading

Yes, different extension. I'm getting the same error on both ad networks so I don't know what the problem is.

AdSense doesn't have a rep, so it's hard to find out what's the reason.
Wait for Infolinks response
If domain was used by someone before you bought it - it could also be banned

Thank you
