K3s dns issue or time-out issue LetsEncrypt?

I am using a k3s single node cluster on a DO vps and I am getting the following error once I add a second domain app to the cluster which tries to resolve a Challenge HTTP-01. I searched the internet and I know sometimes you can get a timeout when you try too many times, but I am curious if this is the case with the following error.

Waiting for HTTP-01 challenge propagation: failed to perform self check GET request 'http://solexclubdecarbidbus.nl/.well-known/acme-challenge/9kdpAMRFKpt_t8SaCB4fM8itLesLxPkgT58RNeRCwL0': Get "http://solexclubdecarbidbus.nl/.well-known/acme-challenge/9kdpAMRFKpt_t8SaCB4fM8itLesLxPkgT58RNeRCwL0": dial tcp: lookup solexclubdecarbidbus.nl on server misbehaving

I think it is internally in K3s and not a time-out but can maybe someone verify? Maybe even put me in the right direction?

Tell me if you need more information! Ty in advance!

Well, I think the entire domain is broken in DNS, see for example:


and e.g. https://unboundtest.com/m/A/solexclubdecarbidbus.nl/G44Q2R2T

Please make sure the domain is functioning first before trying to get a certificate :slight_smile:


My savior! Because of this I was thinking again of an old helpdesk issue at the registrar where they had to change something for this domain. Pretty unique but they had to make a small change at the registry to be able to resolve DNS to my VPS again.

Thanks for your help!
