Sorry for my late response.
Hetzner gave me some strange answer about my IP Address being in Iran but doing an IP location check on it states that it’s in Nuremberg, Germany. As should be the case. So that doesn’t seem to be the issue.
Testing it locally with the same workflow as the server causes no problems and the DHL node has no issues with a socket hang up or time out of any kind.
Testing with curl on my server throws this error:
Looking at the OpenSSL error I’ve found there to be an issue with the default curl version not being able to handle certain OpenSSL 3.0.2 requests on Ubuntu 22.04. Any ideas if that could be the case before I manually update curl?
