I can’t purchase domain with the error message for a whole day. and now the domain(golwbabe.com) isn’t available anymore
Topic summary
A user encountered an error preventing domain purchase for an entire day. The desired domain (glowbabe.com) became unavailable during this period.
Issue Details:
- Error messages blocked the purchase attempt (screenshots provided)
- Domain was subsequently registered by someone else
Resolution Status:
- Domain is now lost to another registrant
- Recommendation provided: Contact Shopify Support immediately when experiencing purchase restrictions or technical blocks to prevent losing desired domains during troubleshooting delays
The discussion remains unresolved as the original domain cannot be recovered.
It looks like the domain purchase failed to a temporary block and your desired domain was already registered by someone else during that time. Next time, please consider contacting Shopify Support for assistance with such a restriction or any issues while doing so.
