The script at the top of this gist (which now contains the modifications from @bloedboemmel) is working for me.
Couple of things that I found helpful:
- Reading the official Namecheap documentation about performing the HTTP GET call to the URL: https://www.namecheap.com/support/knowledgebase/article.aspx/29/11/how-to-dynamically-update-the-hosts-ip-with-an-http-request/
- The detailed instructions from @Dade-R which show the crucial step of adding the executable permission to the PHP file.
Great stuff, and thanks to all involved!
This script is still not working for me. I am using latest copy of the gist and the chmod of Namecheap.php is 755. I even added
file_put_contents('OUTPUT.txt', $fixedXmlString);
to the end of the file so I can see when the script runs and what the output is. When I go to Synology DDNS and enter:
- Hostname: DOMAIN.com
- Username/Email: @
- Password/Key: [Password_From_Namecheap]
and Test Connection, i immediately get failed message and the logs say
ddnsd.c:1741 Fail to update [DOMAIN.com] with IP [XXX.XXX.XXX.XXX] at [Namecheap]
Also, there is no OUTPUT.txt file so the PHP script did not even run.
If I manually run the namecheap.php script and pass in the parameters, it returns good and creates the file, so why does it not work when I run it from Synology?
Edit: I was able to get it working without having to do any sort of file editing.. I went to Synology DDNS > Customize a DDNs service provider:
- Service Provider: Namecheap2 (To distinguish from the other Namecheap script)
- Query URL:
https://dynamicdns.park-your-domain.com/update?host=__USERNAME__&domain=__HOSTNAME__&password=__PASSWORD__&ip=__MYIP__
Then enter in the following settings:
- Hostname: DOMAIN.com
- Username/Email: @
- Password/Key: [Password_From_Namecheap]
Running the connection returns Normal status and actually updates the IP

@aalejaandro Have you tried to change your url back to the original, because yours seems odd to me. Have you tried to paste the original url and your modified url in the browser? Maybe it shows another error.
My fix you mentioned shouldn't affect your issue, it fixed all our errors, when namecheap changed their return format. This time it strangely affects only one person.
My Synology hasn't updated yet, but I suggest to run the php file with a debugger and your input, so you can find any error.
