Not quite there yet but there is progress. Another error msg "421 4.4.5 Too many messages from this host last hour". I may have to try later, however I did notice that once I add the space to my Passport #, error msg "duplicate passport" will occur. I guess I gotta keep adding spaces every time I re-submit?

NEVER get advice from fellow travelers alone, we’re all morons! Good job btw on getting all your documents. I just went through a similar process from Busan to Taipei. Then shorty here after back to Thailand. Luckily I have an agent who is knowledgeable about current travel restrictions and acquiring proper documents. Hope all works out for you as your documents are valid for only 72 hours pre-flight, but again, don’t listen to me, I’m an idiot.
