What should I do after my Non-O visa application was rejected on the eVisa portal?

I think you didn't have enough time remaining on your current stamp to process the Non O based on marriage

1: call the Thailand embassy in Munich for an explanation. The e-visa is available for foreigners who are not in Thailand. It would not be difficult for the Munich embassy to determine that you are in Thailand, not Germany.

2: after receiving your Non-O marriage visa, enter Thailand to activate the first portion of the visa. Shortly after entering Thailand, establish your Thai bank account and fund it with B400k.

3: see 1and 2.

the requirements for the "change of visa type" in case of being married to a Thai wife, is number 6 on this Immigration list

*** firstly, you need to understand the difference between a „visa“ and a „stay permit“ and an “extension of the stay permit”.

As long as you mix up these two different things, you will always get “lost in translation” when speaking with Immigration officials, who mostly also do not keep these two different things apart from each other. In their bad English, a visa for them is the same as a stay permit, and this is so terribly and technically wrong

The Immigration official probably told you to exit Thailand and apply for the 90-days single entry Non-Imm-O Family Visa by the E-Visa system of the Thai embassy in the neighbor country, as you CANNOT use the E-visa online system while you are still inside Thailand

*** you should have applied for the “change of visa type” from a tourist entry to an initial “90-days Non-Imm-O marriage to a Thai wife Visa”

Pre-requisite for this application is you have 400,000 THB sitting in your Thai bank account (no “seasoning period” required at this point, yet), and you got a freshly printed from the Amphur “Kor Ror 22 or 2 (whichever applies) that proves your marriage is acknowledged and registered in Thailand and is still active and valid. Without you marriage registered in Thailand you cannot achieve a 1-year stay permit based on being married to a Thai wife!

You need to have a minimum of 15 days left on your “admitted stay entry stamp” to be able to apply for the “change of visa type”

***and as soon as the 400,000 THB have been sitting in your Thai bank account for 2 months, you can apply for the “1-year Extension of Temporary Stay Permit based on being married to a Thai wife” (which is NOT anything you call "marriage visa" but which is a simple "one year stay permit")

***the fee for the “change” is 2000 THB, and the fee for the application to the “extension” is 1900 THB. And I recommend you buy a single re-entry permit for 1000 THB for the extension of the stay permit, the very moment after it got stamped into your passport

You can't apply for an Evisa when you are in Thailand. And NO, using a VPN won't work. I would suggest going to Vietnam as they have a 5 business day processing time.

You say they asked for a current photo and residence certificate. Are you sure it wasn't worded as "proof of current location"? This is required to prove that you are NOT in Thailand. In our case we uploaded our Airbnb receipt, and then they requested further proof so we had to show our passport stamp (arriving in Vietnam) and our boarding pass from our flight (thank goodness we kept them). Still with that request, the approval came on the 5th business day.

Evisa is not for applying for visas in Thailand. Evisa is for going to a country outside of Thailand and applying through the Thai embassy in that country. If you were in Thailand when you applied, then you were rejected as you should have been.

The immigration officer lied to, or you misunderstood something.
