Domain registration/transfer/renewal order keep failing in PBA while the required operation with registrar has been finished successfully.
- Connectivity problems happened when delivering confirmation letter / response from registrar about completed request.
- Misbehavior at a registrar side.
- API changes at a registrar side.
If you are sure that operations with the domain in question on registrar side were completed (i.e. domain was actually registered/transferred/renewed) use the Domain Conflict Resolver to manually complete failed order in PBA.
