    I tried many things but now I only get the HTTPEND 701 error (which means unknown HTTP(s) error). After HTTPSTART it returns OK.
    My code:

    gprs.at.cmd("AT+QFOTADL=\"https://www.mydomain.de:443/update.zip\"\r\n",1000,print);
    

    I tried many things like setting the port, changing the domain to http, removing the ", but nothing did work. I downloaded the zip provided on RAK's website. Any idea how to deal with this error?
