Can I get a Visa on Arrival at Krabi if I land in Bangkok first?

Hello,

I am travelling to Krabi on 22nd January (day after tomorrow) via don mueng Bangkok. My flight from India lands at Bangkok at 4:10 a.m and I need to board flight to Krabi which is at 6:40 a.m (both flights are Air asia and 1 single ticket) . Given this I have very little time at Bangkok airport to get my Visa on arrival. Can I get Visa at Krabi airport since Bangkok is just a transit point?

I have read various posts saying visa on arrival will have to be seeked at the first entry point, that is don mueng bangkok. Need a clear picture of what best can be done

Any info regarding the above would be much helpful. Thanks in advance
