[Fixed] Our development team has applied a patch to fix the domain check issue. Domain checks should now be working normally.

We have identified an issue with domain check requests to the Google registry (TLDs - .app, .dev, .zip, .day, .rsvp, .mov, etc). This is affecting domain checks via both API and RCP (Reseller Control Panel). Our team is investigating and will apply a patch to restore functionality. We will share another update within the next hour.
