Model: Archer C7  
Hardware Version: V5
Firmware Version:

See below:

 

$ time host elilla.tplinkdns.com


elilla.tplinkdns.com has address 94.220.93.30
;; connection timed out; no servers could be reached
;; connection timed out; no servers could be reached

0inputs+0outputs (0major+787minor)pagefaults 0swaps

 

This delay generates problems when e.g. trying to use certbot to create a certificate:

Hello,

 

You may try to change the WAN DNS server on your C7 to 8.8.8.8 and 8.8.4.4 to give it a shot.

 

BTW, are you still able to remotely access the server via the WAN IP address? Please ensure the DDNS service is still enabled.

 

Last but not least, please ensure the firmware of your C7 is up-to-date.

 

Good day.

@Kevin_Z 

 

My DNS servers are already Google’s. I can update my .tplinkdns.com hostname just fine.  It updates, pings, and it’s accessible, by IP or by DNS.

 

I’m not reporting an issue with my network or my router.  I’m reporting an issue with tplinkdns.com.  It doesn’t happen just on my computer.  It happens on any server I tried, including in other countries.  You can test it yourself with host(1) on your machine.

 

It might be related to the absence of SOA and NS records in tplinkdns.com:

 

$ dig -t NS tplinkdns.com

; <<>> DiG 9.11.5-P4-5.1+deb10u1-Debian <<>> -t NS tplinkdns.com
;; global options: +cmd
;; Got answer:
;; ->>HEADER<<- opcode: QUERY, status: SERVFAIL, id: 62745
;; flags: qr rd ra; QUERY: 1, ANSWER: 0, AUTHORITY: 0, ADDITIONAL: 1

;; OPT PSEUDOSECTION:
; EDNS: version: 0, flags:; udp: 512
;; QUESTION SECTION:
;tplinkdns.com.         IN NS

;; Query time: 1003 msec
;; SERVER: 8.8.8.8#53(8.8.8.8)
;; WHEN: Mi Aug 19 11:19:07 CEST 2020
;; MSG SIZE  rcvd: 42

 

# same results for SOA

 

Or it might be unrelated to that.  In any case, from any network I try, it resolves the host but has a delay, and gets SERVFAIL errors.

@elilla, @Kevin_Z  Hello, I have the same problem when trying to generate SSL certificate. Did you solved it ? I think it is a limitation related to the DNS of tplink.

@Diver15 I could not solve it, sorry.

 

I am pretty sure by now that the issue is that the root domain for tplinkdns.com doesn't have the mandatory NS and SOA records. I've contacted tplink over this, but they didn't want to act on it. In the end I just used another DNS provider.

Hi,

 

I can confirm this issue. Tp-Link should not offer DDNS service if it useless in the current state. It is just really unprofessional.
