    The certificate provider should be Let's Encrypt Prod - Wildcard

    @girish so which steps do I need to go, to get this resolved?

    Btw. I see there some "non-used" SSL certificates, is there any kind of "housekeeping" ?

              @lukas Thanks for the access. I found the root cause. I (re)learnt about Let's Encrypts validation cache.

              <tech stuff>

              It's a very corner case but, unfortunately, it's hit in your situation.

              • You used to have wildcard DNS before. This results in Let's Encrypt HTTP validation (http-01)
              • You switched to Bunny DNS. The code now expects to do Let's Encrypt DNS validation (dns-01)
              • Turns out , Let's Encrypt will "remember" authorization for 60 days (in some places, it says 30 days). So, it will continue to ask for HTTP validation . The code gets confused because is really wants DNS validation.

              If you want to read more:

              • https://community.letsencrypt.org/t/http-01-validation-cache/22529

              </tech stuff>

              I fixed our code to handle this - https://git.cloudron.io/cloudron/box/-/commit/15e0f11bb9815f5e4e7637cf29cf4fd17ccd2da2 . I applied the fix on your server and it seems to work. Atleast, the certs are correct now and we can now go back to checking if AdGuard is working for you. Can you check?

                  @lukas yeah, there is a bug in their API or I don't know how to access wildcard dns entries via their API. I have sent them an email.

                  I have an A record at adguard.cloudron.click. This works:
                  
                  $ curl -H "Content-Type: application/json" -X POST -d '{ "apikey" : "pk1_6e058c5e56b050d8052ee869dbd137857386dcfd403698b46e6d0e7694acf241", "secretapikey" : "sk1_xx" }' https://porkbun.com/api/json/v3/dns/retrieveByNameType/cloudron.click/A/adguard
                  
                  {"status":"SUCCESS","cloudflare":"enabled","records":[{"id":"313173661","name":"adguard.cloudron.click","type":"A","content":"89.58.59.112","ttl":"600","prio":"0","notes":null}]}
                  
                  
                  I have an A record at *.test.cloudron.click . This does not work:
                  
                  $ curl -w '%{response_code}' -H "Content-Type: application/json" -X POST -d '{ "apikey" : "pk1_6e058c5e56b050d8052ee869dbd137857386dcfd403698b46e6d0e7694acf241", "secretapikey" : "sk1_xx" }' https://porkbun.com/api/json/v3/dns/retrieveByNameType/cloudron.click/A/*.test
                  
                      <div id="container">
                          <h1>An Error Was Encountered</h1>
                          <p>The URI you submitted has disallowed characters.</p>        <p>You can probably find what you're looking for on our <a href="/">homepage</a>.</p>
                      </div>
                  400
                  
                  I tried with percent encoding but that does not work either:
                  
                  $ curl -w '%{response_code}' -H "Content-Type: application/json" -X POST -d '{ "apikey" : "pk1_6e058c5e56b050d8052ee869dbd137857386dcfd403698b46e6d0e7694acf241", "secretapikey" : "sk1_xx" }' https://porkbun.com/api/json/v3/dns/retrieveByNameType/cloudron.click/A/%2A.test
                  
                  {"status":"SUCCESS","cloudflare":"enabled","records":[]}200

                  Hey @girish,

                  I have the same problem now. I was a bit too stupid and first created a manual record in Porkbun which is logically not necessary and does not work. I have subsequently deleted this entry again. I tried via Cloudron (with Lets Encrypt Prod/ Wildcard and Porkbun DNS) to set an alias entry for AdGuard (*.adguard.mydomain.com). However, I get this error message:

                  GET /api/v1/domains/my.domain/dns_check?subdomain=*.adguard 424 Failed Dependency Porkbun DNS error 400 {} 770.306 ms - 76
                  

                  I ran the DNS sync function in Cloudron, as well as renewed the certificates. However, nothing has helped

                    @ByMynix Porkbun support never got back to us and we gave up trying after reminding them 2-3 times. Their API is broken wrt wildcards (well, atleast it's undocumented). I recommend using some other DNS provider if you want this feature.
