[Solved] Can't update my IP for dynamic DNS with curl or wget

Dear community,

I registered two domains at Namecheap and want them both to point to my daily changing IP. I know, there is DDclient, but it looks like it's not maintained anymore and it does not work with multiple domains. Fortunately, Namecheap offers a "browser update method" where I can just use the URL: https://dynamicdns.park-your-domain.com … mypassword.
This works just fine using firefox on my laptop (also arch), but I want it to be automated on my archlinux (ARM) server with cron. As some scripts on github suggest, I could just use curl followed by the URL to update my IP. Unfortunately, I always get an error that I do not understand:

[amo@AmoNotebook ~]$ curl https://dynamicdns.park-your-domain.com/update?host=@&domain=fickmonsta.de&password=********
[4] 24143
[5] 24144
[amo@AmoNotebook ~]$ <?xml version="1.0"?><interface-response><Command>SETDNSHOST</Command><Language>eng</Language><ErrCount>1</ErrCount><errors><Err1>Domain name not found</Err1></errors><ResponseCount>1</ResponseCount><responses><response><ResponseNumber>316153</ResponseNumber><ResponseString>Validation error; not found; domain name(s)</ResponseString></response></responses><Done>true</Done><debug><![CDATA[]]></debug></interface-response>

At this point I have to cancel the operation using ctrl+c and then I get this:

[4]   Done                    curl https://dynamicdns.park-your-domain.com/update?host=@
[5]   Done                    domain=fickmonsta.de

I get the same error on both my laptop and the server, and with both curl or wget. I already spent 3 hours in chats with the namecheap support but apparently on their side everything is fine and they confirmed that it sould work the way I try with curl.
Does anyone have an idea?
Thanks in advance!
Amo

your shell is expanding the & character: put quotes:

$ curl "https://dynamicdns.park-your-domain.com/update?host=@&domain=fickmonsta.de&password=********"
