Hello,

I installed LEDE on my WRT1900AC v1 and now am trying to get ddns working.
My prerequisites:
- linksys WRT1900AC v1 as router
- router is situated behind ISP-modem (Fritz!Box 7412)
- ddns-provider spdyn.de
- domain/user/password working in earlier firmware-versions (openwrt CC/DD)
What I did:
- installed LEDE v17.01.2
[...several other configuration stuff...]
- installed ddns-scripts luci-app-ddns ca-certificates curl

During luci configuration I wasn't able to use the preconfigured "spdyn"-entry from DDNS Service provider [IPv4], I would always get a domain/user/passwort-missing warning. So I chose the "custom"-entry.

Now I get the following picture:

and the corresponding log-output:

Error 48 is "unknown"/app specific, so I don't know exactly what went wrong. Obviously the ip-check doesn't work...
Any help is appreciated!

Thanks at least for reading,

From the log you can see, that curl cannot detect your WAN IP by calling "http://checkip4.spdyn.de/"
Does this work from your browser ?
Do you need to detect your WAN IP via web ? Normally it's better to detect via "network" or "interface".

Yes, you're right.
It does work by browser - what I forgot to write in my starting post: the router is situated behind my ISP-modem (Fritz!Box 7412).

The very same configuration works seamlessly for a TP-Link TL-WR842N/ND v1 and OpenWrt Chaos Calmer 15.05.1.

Please have a look here, it might help

I never had problems when libcurl was compiled using OpenSSL.
The curl problems started with the decision to use PolarSSL now mbedTLS as default SSL.

If not really needing curl move to wget-ssl

No, I actually don't really need curl.
Thanks man, that made my day! :-) With wget it works instantly!
