The reason and solution of "failure to connect to the server" prompted by pagoda one click migration

Today, when I was doing server migration for a customer, I used the "Pagoda One Click Migration API Version" of the Pagoda“ https://www.bt.cn/bbs/thread-42566-1-1.html ”After the operation, click Next to directly prompt "Failed to connect to the server".

However, it is normal to ping the new server, and the pagoda panel of the new server can also be opened for access.

After carefully looking at the pagoda official one click migration tutorial again, we carefully compared the "panel address", "API key" and "IP whitelist", and found no problems.

Then I carefully looked at the address of the lower panel. Is it a problem with https? Why is https automatically added to the newly installed pagoda panel? Obviously, they have not applied for ssl certificates.

So I changed the "https" of the panel address to "http" and found that an error was reported.

Then turn off the "Panel SSL" in the pagoda panel of the new server:

Finally, change the panel address in the pagoda one click migration API to "http+server ip+port", and click Next, success!

The reason for this problem is that the newly installed pagoda panel will enable ssl by default, but there is no corresponding ssl certificate.
