I recently purchased a domain (.io) on Sedo. The seller has provided the auth code, so all good to go. Initially attempted to transfer into GoDaddy, as I have done a million times before. However, GD's transfer tool simply wouldn't recognise the domain as being eligible for transfer. Nothing about it being locked or anything - just a simple message saying not eligible. Looked at whois records, and nothing in there would suggest any sort of problem (not changed registrars for years, status ok etc). Then tried NameCheap - their systems report the domain as eligible for transfer. Enter auth code and proceed, but shortly after get an email saying transfer cancelled due to invalid auth code. What's going on? If it was just the auth code I'd suspect just an error somewhere, but the fact GoDaddy won't even recognise the domain seems odd. Have gone back to Sedo to query auth code.
