Among several subdomains, I have node servers running on different ports. I have a subdomain called alexa-service.healform.de, which runs a node server that should execute some functions and requests. One function of this is a GET query of data provided by another subdomain, hosted on my server too - oauth2.healform.de. If I let this function run, I get the following error message in the terminal and that is also the curious part:

Error message:

Hostname / IP does not match certificate's altnames: "Host: localhost." Is not in the cert's altnames: DNS: ampinbaunatal.de, DNS: www.ampinbaunatal.de "

When I saw that, I thought I was asking AskUbuntu rather than Stack. The domains ampinbaunatal.de and www.ampinbaunatal.de are also hosted on my server and also have a valid SSL certificate issued by Let's Encrypt. But why does the function of oauth2.healform.de differ on ampinbaunatal.de? The domains have nothing to do with the function.

When I call the endpoint of the data, the function should retrieve, with Postman, I get a correct response. But as soon as I run the API query in localhost via the node server (I'm on Ubuntu Server 18.04 btw.), it somehow switches to the other domain and I get this error message.

Does anyone have an idea what's wrong with the certificates? Both have valid SSL certificates. And why does he accidentally switch to the ampinbaunatal.de domain?
