I don't think your PC/MAC is the WebDav server. But 127.0.0.1:5006 like in your configuration points to the local System and not to your Server.
Possible you have a DNS problem, because your Server DNS name is resolved to 127.0.0.1

Thanks,and how can I fix this, can you tell me more detail?

Do you know the URL or IP address of your WebDAV server? You should be able to check it on the other Windows PC you say is working. Having one working system means you are ideally placed to troubleshoot this by comparing them in detail. Find the server's address, check connectivity and you should be good to go.

No, because this is not really a Joplin problem.
The DNS name (configured Synology name) is resolved incorrectly on the computer.
