Strange SSL certificate error in endpoints


Dear community,

i’ve a strange problem with http"s" calls in endpoints.
If i call a website with LetsEncryt certificates, i’ve got on some websites an “Error 500 (certificate verify failed)”. For example on When in call website of LetsEncrypt itself there is no error.
Both sites uses regular LetsEncrypt certificates, both sites are green in every browser and both sites do have the same certificate-path with same root authority.
This problem is and my local thinger server.

Does anybody know about this issue? Is there a chance to see in any logs what happend in detail?

Regards Marcel


Hi, yes, there is a problem with such certificates in the current version. We have a private version with a fix, but it has not been released yet, as we are so busy preparing a major release, so, stay tuned :wink:
